Passing values from PowerApp to PowerAutomate and backwards

[DarkTrinity]

Hi Community,

I would like to write a program that does some more complex string manipulation. The way strings shall be manipulated is depending on 2 different values, stored in formulars as below:

Power App:

1. has a textfield, containing value 1
2. has a slider, containing value 2
3. has a button to start the programm (the power automate flow)
4. has another textfield, where the manipulated string shall appear in the end

Power Automate:

1. Shall do the string manipulation
2. And give the result back to Power App into a textfield (as per point 4 above)

I am aware how to pass values to a Power-Automate Flow, but I would know how Power-Automate can give results back to the Power-App, so that these are stored in the textfield.

Is that possible in general and is there some documentation somewhere ?

Thank you in advance

Its still not working. I could send the generated value by email to the user as a workaround - but that is not waht we really want. we like the value in the app.

but it just not working.

Here the app:

Here the flow:

Hi @DarkTrinity ,

Can you please share the Error text you are receiving? So far the only thing I can see is a case mismatch (hash vs. Hash).

I have 2 issues here:

Beside: I am wondering where you guys have all this knowledge from... I am really no newbie when it comes to scripts and coding. I mean - is there maybe somewhere a compendium I missed to find (beside the MS docs, which are in my oppinion in most cases not that helpful)...

And regarding "Hash" and "hash" - i have overwritten "Hash" into "hash" 10 times now and saved. But still it is saying "Hash"....

Hi @DarkTrinity ,

Apologies, made a typo:

Set(
   varHash;
   Generate.Run(
      fld_word.Text; 
      Slider1.Value
   ).Hash
)

In my case the knowledge comes mainly from watching videos, making lots of apps and this community.

Now I am having 5 issues .... The targetfield, where the value shall flow in, has now an error too.

If I look into the flow's hisstory, I see it's not even being started anymore ^^

Hi @DarkTrinity ,

This one then?

Set(
   varHash;
   Generate.Run(
      fld_word.Text; 
      Slider1.Value
   ).hash
)

Please include the formula that's giving the errors as well in your posts, since some things don't seem to add up.

Yes, it seems to work this way:

Set( varHash; Generate.Run( fld_word.Text; Slider1.Value ).hash )

All in one line, no linebreaks, etc...

However... I think I also start watching some videos...

HI @DarkTrinity ,

Good to see this is working. Line breaks and indents do not affect how formulas are evaluated in Power FX, similar to HTML. I actually use those a lot to improve the readability of the formulas.

However, Power FX is case sensitive so it was case mismatches (text vs. Text and hash vx. Hash) that were causing the issues at the end.
