User registration with different actions

[Bhairav_Valera]

I am trying to use a page in my app (frontend) to register users into my backend system. I have a spreadsheet that records user info which is then passed through to the backend via cloud functions on the Google Cloud Platform.

Ideally, if the current logged-in user hasn’t been recorded in the table yet, then an “Add” action would be present such that they can register with their info. If the current user however has registered prior, an “Edit” action would be present such that they can change whatever info they previously inputted.

This is similar to a question that I had asked previously, namely this but the solution here doesn’t seem to work anymore. That is, I’m using

ISBLANK( FILTER( table , [email column] = USEREMAIL() ) )

for the “Add” action and

ISNOTBLANK( FILTER( table , [email column] = USEREMAIL() ) )

for the “Edit” action. But this only seems to work with the “Edit” action on not the “Add”. In other words, if a user is brand new to the app, they can’t register their info. Any particular reasons as to why this may be happening?

Your help is appreciated!
