Hi all,
I spent few hours looking for an answer to my problem, unsuccessfully (I'm probably unable to find the proper request terms)
So I have this flow triggered from a button in my Powerapps.
The problem is (as amny users) with the "Assigned to:" field 
On the powerapps part I'm calling the flow this way (screenshot 2)


How can I solve this ? I don't find a way to split the Approvertoemail 😕 Should I put a ForAll in the Btn_Submit onselect method ? Or is this a way to avoid the check of the format by the flow ?
Thank you in advance
Fred
