Hello, I am trying to build a flow that will replace a patch function I am using within power apps to update a SP record.
The data i am sending to SP is in a form. The sample Identifier field is the unique field I am currently using to find and update the SP record with patch.
The issue is that this does not always update the record. I need to send the same data through a flow to guarantee the record will be updated every time. I was reading another tutorial that assigned the data in the power apps for to a variable, then used those variables to update the record. However, when I try to do this, I am not able to use the variable as the unique ID.

I may be going about this all wrong. Any help is greatly appreciated.
