I’m not a very computer savvy person, but I managed to create an attendance app.
Now, I have done something that has disturbed my attendance table → it records the absences still, but all of my columns listing or pointing to the PRESENT students in some way are empty. I don’t know how to fix this and I’m getting desperate 
I know this isn’t much to go on and I can give more information if asked the questions but I’m really trying not to lose my mind right now.
