Checking user name from other source

My app’s URL:

Hello guys,
Thanks for your answer, maybe i just don’t how to do that -_-

I just want to rephrase to be sur to be understandable :grinning:

In my “live” tab from “race live” source in my table, i would like to show specific button if the current user fill up his pseudo wich is from “membres” source in my table (user data)

Thanks in advance :slight_smile:

Maybe by using an IF column and a visibility filter.
The IF column checks if the value you need is empty or not.
The visibility filter is activated only when the IF column is TRUE.

Does that work?

Check this out.

Thanks so much
