Working with Variables in Apply to Each

Hi all,

I think I should know this but I just can't get there.

I have 2 apply to each loops. In the 2nd loop, I'm appending to a string variable a name, I then get the outputs of this variable in the 'Compose' below it, which is outside the 2nd loop but still inside the first loop. I'm using append because if there's 3 names in the 2nd loop I want to append the 3 names together.

This works fine for the 1st loop, however, when the 1st loop moves on to the next value the append variable updates with more names - this I don't want!

What I'm looking to achieve is for the variable to store all the names from the 2nd loop but not all the names from the 1st loop - just the 2nd loop and reset for each 1st loop.

Maybe append to variable isn't the right approach here?

I hope that makes sense!

Hello @Anonymous ,
you can use two string variable, one of them to use temporary.
So, you can append all the values to the temp variable, copy it in the def variable and clear the temp variable values.

In that way, you can grab only the names you want.

Hi @MarconettiMarco,

How do I go about clearing the temp variable values?

I thought it was as simple as setting the variable to null at the end of the flow but that didn't work - so I tried appending the variable to null and that didn't work either.

See the image below - the "Clear Participants" is setting the variable to null at the end of the flow but the variable is still appending across the 1st loop

This is how I did and it worked for me.
Initialize Your Variables: Start by initializing your variables. You will need two string variables: one for temporary storage and one for the final result.
Create a variable for temporary storage. Let's call it "TempVar."
Create a variable for the final result. Let's call it "FinalVar."
Append Values to the Temporary Variable: Use the "Append to string variable" action to add values to the "TempVar" variable. This action can be used within a loop or any other relevant context where you are collecting values.
Copy Temp Variable to Def Variable: To copy the values from "TempVar" to the "FinalVar," you can use the "Set variable" action. Set the value of "FinalVar" to the value of "TempVar" using an expression like variables('FinalVar') = variables('TempVar').
Clear Temp Variable: To clear the values in the "TempVar," you can use the "Initialize variable" action with an empty string as the initial value. This will effectively clear the temporary variable. For example, set variables('TempVar') to an empty string ''.
Repeat as Needed: Repeat steps 2 to 4 as many times as necessary within your workflow to accumulate and copy the values you want into "FinalVar."

Initialized two variables
Rest of the flow.

Result:
