If statement expression with dynamic content

[KellyHickman]

I have Create Item to Sharepoint operation set pulling responses from a Form, I would like to populate data in this Create Item operation in a field titled "Deep Link" based off an If statement from another field titled "Request Type".

If Request Type equals "deactivate a course", then the Deep Link field should show nothing, just empty value. If "deactivate a course" is False, then the Deep Link field should show text "Deep Link".

After googling and reading posts here on the forum, this is what I've come up with but I know it's wrong. 

if(equals(outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11']),deactivate a course), ' ', 'deep link')

Any help would be greatly appreciated!

Hi @KellyHickman 

Almost!

You are simply missing single quotes around deactivate a course. It should be:

if(
	equals(
		outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11'],
		'deactivate a course'
	),
	 '', 
	'deep link'
)

[KellyHickman]

Thank you for responding, it's still telling me it's invalid expression 

if(equals(outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11']),'deactivate a course' ), '', 'deep link' )

I'm adding it as an expression to the Deep Link field, it should work there, right? Or is my logic off?

[DJ_Jamba]

Where exactly are you putting this code?

[KellyHickman]

I want the expression to go into this field. 

So I either see nothing, no text,  in this field or the text "deep link".

[DJ_Jamba]

Is that a text field or multiple lines of plain text or rich text or something else?

[KellyHickman]

The list settings from Sharepoint say Multiple Lines of Text.

[DJ_Jamba]

Can you add a compose before that create/edit action and add the formula expression:

outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11'])

Then add a terminate action to stop the flow there

[KellyHickman]

I appreciate your assistance! I've performed this step, created the Compose and Terminate directly after. Then I went back to the deep link field and entered this expression:

if(equals(outputs('Compose'),'deactivate a course','','deep link'))

It allowed the expression this time but when testing it returned error message:

Flow save failed with code 'InvalidTemplate' and message 'The template validation failed: 'The template action 'Compose' at line '1' and column '6880' is not valid: "The template function 'outputs' is not expected at this location.".'.'.

[KellyHickman]

I figured out my error on that InvalidTemplate issue above, but now I have a different one: 

Unable to process template language expressions in action 'Create_item' inputs at line '0' and column '0': 'The template language function 'if' expects three parameter: the condition to test as the first parameter, the value to return if the condition is true as the second parameter, and the value to return if the condition is false as the third parameter. The function was invoked with '1' parameter(s). Please see https://aka.ms/logicexpressions#if for usage details.'.

[DJ_Jamba]

It's because you were referencing the test code outputs('Compose') instead of 

outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11']

So the next error is that an If statement requires 3 parameters

Something to check/evaluate,
What should happen if true
What should happen if false

Example:

if(
      equals('one','two'), // Something to check: Does 'one' equal 'two'
      'yes - correct', // if true 
      'no - incorrect' // if false
)

According to the error message (The function was invoked with '1' parameter(s).), you have only provided 1 parameter e.g.

if(
      equals('one','two') // Something to check: Does 'one' equal 'two'
)​

[KellyHickman]

Detailing this out per your notes: 

if(equals('response type' (one),'deactivate a course' (two) ), // Does ' response type ' equal 'deactivate a course'?

'yes - returns nothing ' ' if true

'no - 'deep link' if false

if(
      equals('one','two'), // Something to check: Does 'one' equal 'two'
      'yes - correct', // if true 
      'no - incorrect' // if false

So this should be the correct expression? The parentheses don't seem right but I'm following your logic above.

if(equals(outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11'],'deactivate a course'),'','deep link'))

And where does the Compose function come in that we added? When I included the terminate action it just stopped and didn't complete the flow, so I took it out, I must have done something wrong.

[DJ_Jamba]

That looks correct and same as the original suggestion:

if(
	equals(
		outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11'],
		'deactivate a course'
	),
	 '', 
	'deep link'
)

What I'm trying to check is if outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11'] is a  table, a record or a single value (I think it's a table or a record ).

So right after action get response details

Add a compose.
Click inside the compose. In the box that pops up on the right, select the Expression tab and enter:

outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11']

Then don't forget to click the OK button

Then add a terminate action. It should look like this:

What is in the compose action when you do a test run?

[KellyHickman]

Is this the screenshot you want? It ran successfully and stopped at the terminate trigger. 

I really appreciate you walking me through this, can't believe you haven't given up on me yet!

[DJ_Jamba]

😀We'll get there! I need food though so will have to shoot off soon.

Right so it's a value.
2 things left.
In that same compose action change the expression to:

if(
	equals(
		outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11'],
		'deactivate a course'
	),
	 '', 
	'deep link'
)

Leave the terminate action there. 
It should be blank when you do a test run.
Is that the case?

[KellyHickman]

I typed this into the Compose action:

if(equals(outputs(outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11']),'deactivate a course'),'','deep link')

It gave me this error. Does it not like my attempt at returning a "null/blank" value?

Flow save failed with code 'InvalidTemplate' and message 'The template validation failed: 'The template action 'Compose_Request_Type' at line '1' and column '6977' is not valid: "The template function 'outputs' is not expected at this location.".'.'.

[DJ_Jamba]

You have two outputs in your code.

If(equals(outputs(outputs(

Can you copy this and paste this in the expression?

If(
equals(
outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11'],
'deactivate a course'
),
'',
'deep link'
)

[KellyHickman]

Oh for heavens sake 🙄 Can't believe I missed that....

It worked!!!

Now what? remove terminate and what expression to add to the Deep Link field in the Create Item action please?

[DJ_Jamba]

Whoop! 😀

Last step before you go back to the Create item.
Change the expression in that Compose to this:

If(
equals(
outputs('Get_response_details')?['body/r47fb301111e74dc4b0abe7bd26b23e11'],
'deactivate a course'
),
null,
'deep link'
)

When you run it again, the compose should output null?

[DJ_Jamba]

No sorry - it should still be blank 🙄
