I have 2 option buttons one called "Min" and one called "Reg". When i click on the "Min" button it inserts "=Settings!M3-J2" into cell K2. When i click "Reg" button it deletes anything that is in cell K2. What i would like to be able to do is if cell K2 does not equal "=Settings!M3-J2" then uncheck "Min" button and check "Reg" button. In ohter words the "Reg" button should always be check unless cell K2 equals "=Settings!M3-J2". Does anytone know if this is possible.
