I know that because onEdit() is a simple trigger, you aren't allowed to access other files.
My code requires that a different sheet be grabbed and stored (a sheet with a bunch of information), and then every time a user makes an edit on the sheet the script comes from, it runs the onEdit() code.
My original code won't work because the onEdit function is asking to retrieve that other sheet, which is a no-no.
However, couldn't I just have the other sheet (the one with info) declared stored as an array and then declared as a public variable (before the onEdit function), and then reference that in the onEdit function?
Thats what I thought I could do, but it doesn't seem to be working...
