would still like a way to only tick one box at a time though.
Ok, that greatly complicates things!
If that is your goal, to only be able to select one "checkbox" (cell with a
tick mark) in the range N11:N14, then I would use option buttons. Only one
option button can be selected at any time. To do this is completely
different from what you have done so far.
The first thing you would want to do is to delete that sheet code.
Right click the sheet tab and select View Code.
In the VBE, goto Edit>Select All
Then Edit>Clear
Then close the VBE
Now, setup the option buttons:
Back in the Excel worksheet:
Right click any toolbar
Select Forms
The Forms toolbar should appear
The option button is the one with the black dot in the middle of a "circle"
Click on that then move your cursor to cell N11
Left click and the option button is "dropped" in that location
Now, adjust the size and placement to get it exactly where you want it
Repeat the process for cells N12, N13 and N14.
Now, if you want to use the status of which option button is selected as a
condition in a formula:
You have to link the option buttons to a cell:
Right click any option button
Select Format Control
In the Cell Link box enter a cell location. Whenever an option button is
selected, the linked cell will tell you which button is selected. It will
display the number of which button is selected.
Then you can base your formula on the value of that linked cell.
If you get "lost" and would like me to do this for you just let me know how
to contact you.
