I have a formula in a cell check box:
=IF(COUNTIF(b3:b4, true) > 0, true, false)
It works great, but when you click on it, the formula is removed. It can be pressed accidentally, so I would like to protect myself.
Nothing checked.^|^
Only Monday3 is checked, and also Monday2 checked automatically. ^|^
I checked Monday2, and nothing else ^|^
Monday2 not working after checking(((((^|^
