I'm currently working on a sheet that has a "Total" stat on it which will represents slots and I want that total slots number to be deducted by "1" every time a tick box is checked.
For example, there are 8 total slots and there are 8 Tick Boxes, each time a slot is consumed, a box is ticked and the total remaining slots is deducted by 1.
What would be the best way of making this happen? I understand I can enable "iterative calculations" and have something like
=SUM(F15,IF(F15>0,SUM(IF(K15,-1,0)+IF(L15,-1,0)+IF(M15,-1,0)+IF(N15,-1,0),0)))
I'm a total spreadsheet noob but there has to be a more consolidated way to do it.
