My app is not sending data to spreadsheet

I am creating an app which gets the device ID from airtable spreadsheet…
If Device ID is already registered, the user will be redirected to home page else, he/she will be redirected to login page…

In login page, the app does not store data in my airtable spreadsheet…

What to do?

Here are screenshots of:-

1.) Blocks
2.) Airtable base

You’ve to store data on sign up, in order to compare that while logging into app.

Actually it is the sign up page…( I accidently wrote login)
