@Senthil_Seveelavananan & @Luis_Retana an example would help understand what you’re looking to do, but here’s something that has worked for me.
Create a user table
[_users], and have a column for each user’s attendance
[Attendance], true or false checkbox.
Then create a formula ‘
user’ that maps to the logged in user:
Then have a button which can toggle the attribute for the logged in user:
ModifyRows( User, _users.[Attendance], User.[Attendance].Not() )
You can even get fancy and have the button’s label be dynamic:
If( User.[Attendance], "Attending", "Absent" )
