Make a FileMaker Pro check box behave like a radio button

I have had this issue and being on this page you likely have it now or have had it in the past. Radio buttons are great but they actually can be a slight annoyance for some users. Especially when they want to clear out the content. Normally you just click on the field and hit delete on your keyboard, though that is far too many key strokes for our busy busy world.  So in comes check boxes but how do you get the check box to behave like a radio button ?


In your field definitions just go to the field and under options assign it an “Auto-Enter Calculation” and add GetValue(Self; ValueCount(Self)) into the calculation box. Make sure you turn off the “Do not replace existing value (if any)”, if you don’t turn it off this technique will fail.
