I am attempting to develop an app to reward students with digital points that can be spent for prizes. I have a google sheet set up with all the information needed: first name, last name, id number, class period, and amount of points. Each student will carry a "debit" card that will have their id number in the form of a barcode on it.
I want to scan the barcode and have the app display the information and the option to add or subtract points from their "accounts" in the google sheet.
I have worked on this and have gotten different aspects to work. I have now confused myself so much from the research and different trials that I don't even know where I am.
I will attempt to add my pics. Please help if you can. Ask if this isn't clear enough. I will try to explain the best I can. So confused!!

I get his error going from Screen1 to StudentInfo
ScanScreen: Has scanner and text box with the idea to go to studentinfo screen
StudentInfo Screen: Displays the information in a formatted way and has the ability to add/subtract points to a google sheet and updates
