Displaying data from spreadsheet based on what the user has signed up

[hay.ruwn.neiysaj]

hi. ive looked hard enough but i dont seem to know why i cant display the data from spreadsheet. sorry if the problem has been solved before

1. first the user has to sign up, when signing up they hv to fill in their detail (name, faculty, stdents ID) that will automatically updated in the spreadsheet.
2. i have another screen “profile” where it displays the logged in user’s fullname, faculty, and student id.
3. when i test it, it didnt display the data.

my sign up blocks:

my “profile” blocks and interface:

The block already a user? should not work. You can’t use a green block outside of it’s parent block.
