For some reason, a proper validation of a yes/no checkbox on a form is eluding me. I've created a validation rule of: 

to trigger a message to check the box, but the validation doesn't trigger. I've tried using values of no, No, False, false, FALSE, and even tried coming at it from the other way, e.g. {Self}!="Yes"   
I've verified that the field contents properly get stored as "No" or "Yes".   What gives?
