Hi,
I have a PowerApp with a combobox where a user can select 1 to n different companies.

I need to pass on those values to a Flow.
Because I don't know how many elements will be selected, I created a single compose element in Flow that should hold a string that separates the different companies by a comma.
The question is how to embed the different elements into the Flow run equation that is selected in the PowerApp?
The problem is that I can enter only a single text that I hardcoded in the following screen to "0100"

If I replace "0100" with the combobox selection then I get an error because of the multiple elements that are selected.
Question: Is there a way to put the different selected companies into a kind of container that I then enter in the Flow run equation?
Would be great if one could help.
Many thanks,
Ludwig
