the editor does not allow to edit the line
What happens is that we have an incorrect , (probably because an override was needed) just after a function we made in an event and before the function of another event.
But when you go to the code that contains the incorrect , you cannot delete it, because the line that contains the , is not there.
The line 192 does not appear when you edit the code to remove it from the event.
The code only displays line 0 to 191.
