I'm progressing on my endeavor to learn PowerApps and I have been working on the sample Expenses template. I have remade the built-in sample collections to SPLs. Im having trouble with the NewLineItem Screen, on the button fx, I do not show an error but when I click the button after adding data, it works properly and data is addded to the SPL, however the lookup column "ReportID" is not being populated.

Can anyone help me understand what is happening?
