Hello,
Im making a time-out app in powerapp, i have a gallery where all the checked in students are displayed, on another screen i have another gallery where the details of the selected student are shown, in that screen i have inserted a (Attendance CheckBox) it is automatically checked because when the student scans the qr code linked to the time-out their details get written to a excel file and he is automatically checked in.
Now i want to have the option to uncheck the checkbox and write to excel file in column (CheckedOutByTeacher) that the student left, i got that working but when i leave the StudentDetail screen and then go back the Checkbox is again checked while the student is actually not checked in.
Also, i have multiple students checked in at the same time, if 1 of the checkboxes is unchecked they are all unchecked and i dont want that i want to specify for each student if he left the time-out or notThis is the first gallery where all the students can be seen who are checked in in the timeout, if you press on the arrow on the right you go to the DetailScreen of that Student
