How to set a condition to a false checkbox
I’m currently doing a wedding costs spreadsheet and have successfully managed to figure out how to make a “true” checkbox deduct deposit paid from a balance, however i am now struggling to make a “true” checkbox for balance paid revert the balance to 0. I therefore added a 3rd column called “still to pay” to try and make this easier and now that successfully reads 0 when the box is checked, however when the box is unchecked it states FALSE. How do i work around this? I would want when unchecked it to display the “balance left to pay” figure as i of course would have the sum of “still to pay” displayed as outstanding wedding costs! Hope this makes sense.
The following screenshots are:
1) a successful ticked box which reads 0
2) an unchecked box which reads FALSE
