Hello all,

newbie powerapps dev here. When creating a canvas app for my employer, I ran into an issue.
Whats the app about: Its an internal event booking app.

- user can sign into events

- or they can also cancel their participation

And the 2nd point is my problem. I have figured out a way how to add person into the column without deleting all previous users.

Sharepoint screenshot:

This is how I add the person in the column using collection:

This is how I tried to remove 1 person from that column, but it just doesnt work: Basically I tried just reversing the process.

Can any1 help? 🙂

Thanks all.

Wait for the expert but here's what I see now, didn't you just put back the same value from this code?

Hello,

Yep, my earlier suggestion would really not fix it. but can you try this code:

To remove:

Remove( colPrihlasenych, LookUp(colPrihlasenych,Email = User().Email));

To patch the data:

Patch( Booking, Lookup( Bookings, ID = BrowseGallery1_1.Selected.ID ), { Prihlaseno: colPrihlasenych } );
