So I'm trying to accomplish a couple of things.
First:
A. I have a text input box on a (Thank You) screen and a user would type in their email address and click a button to patch it to the sharepoint list.
1)Criteria for where to record is that an input box on the 2 screen (Lookup Info Screen) matches an ID number in the SP list.
What I have for a button to patch this info to a SP List:
DisplayMode = If(Not(IsMatch('TxtInput-StEmailAddress'.Text, Match.Email)), DisplayMode.Disabled, DisplayMode.Edit)
OnSelect = Patch('ThankYouCardList-Student-Donor', LookUp('ThankYouCardList-Student-Donor', Student_ID = sbox - ID),{TxtInput-StEmailAddress: {TxtInput-St_Email'})

part of the Sharepoint list"
as you can see there can be multiple records this email address needs to be patched into.

This is the screen that the "ID" gets checked against the SP list.
The Type ID here input box is then verified with an existing record in the SP list. I call this input text box "sbox - ID"
