Get variable column data from sharepoint, using column name from flow.

[Anonymous]

Ok, so this is probably something unbelievably stupid that I'm missing, but I'm drawing a blank, and 3 hours of googlefoo is failing me

I have a SharePoint list with columns for various countries, and i want to create a dynamic lookup so given a country from the triggerbody i can get a specific value from the relevant SharePoint column.

Something like this.

Get item from sharepoint (works perfectly - filtered by *ITEM*)

Apply to each item (works perfectly)

items('Apply_to_each')?['*COUNTRY*']

But I can't get either set/initialize variables or Compose to show the correct output, they all show the text "items('Apply_to_each')?['*COUNTRY*']" rather than the value.

Am i missing something painfully obvious?

Can you share a screenshot from your current flow design?

Thanx!

Sure!

The text value is correct, i just want work how to get it to pull the value, rather than the text.

Hi!

I think the problem is, you are adding WDL expressions as regular text. For example...

items('Apply_to_each')?['China']

...is also a expression, so you need to add it following the steps described here:

https://flow.microsoft.com/es-es/blog/use-expressions-in-actions/

Can you please also share your trim() based WDL expression and explain briefly what you wanna calculate with such expression?

On the screenshots share I cannot see its details

Thanx!

Hope this helps

well yes, that's the problem, I don't want the text, I want the expression.

The trim is a horrendous thing, but it pulls out the country required. it pulls out the country name from the trigger body. in the example i posted earlier, it was "China"

trim(substring(triggerBody()?['po_configurationdetails'],add(indexOf(triggerBody()?['po_configurationdetails'],'TEXT 24 chars long'),24),sub(indexOf(triggerBody()?['po_configurationdetails'],'MORE TEXT'),add(indexOf(triggerBody()?['po_configurationdetails'],'TEXT 24 chars long'),24))))

What i want to do then is using a "get items" from a SharePoint site get the value from the column named "China"

If you happen upon here, this may be what you are after:

Identify which SharePoint item columns were updated in Power Automate (tomriha.com)

Get previous value(s) of modified SharePoint column(s) in Power Automate (tomriha.com)

Any answer to this in 2023? Still a relevant problem with many applications

Obviously this post is old, but I had been searching a few posts like this and never found a simple solution that really answered the question.  Here is how I handled what the OP asked.  If you add a filter array just before 'Set Variable 43' and split the item returned from 'get items 5' into an array, then put your trimmed country name in as the filter, it will return the country AND its value.  Then where you have put the trimmed country name inside 'Set Variable 43' you can put in a substring of the newly inserted 'Filter array' just above.  My example is very similar i just got the column name from my trigger in this test.
