Did some fixes to the spreadsheet again. people keep messing with it. Also people are keep doing the ascending/descending. I don't really care which one we use but it's pretty annoying haha
Gise87, If I'm not wrong, as the sheet owner, you could "protect range" of cells and setting a different permission for specific cells... It would help reduce the messing up...
cheers.
