Try using Radio Buttons instead... but if you insist on using checkboxes I
can write a code that would only allow one checkbox to be checked.

I am trying to format an excel spreadsheet that contains three checkboxes for
one particular question.

My goal is to link all three checkboxes listed for (yes, no, N/A) response
to only allow on box to be checked for an answer.

Is there a way to format this in excel?
