Ok, I have a Radio Box that's basically a Yes/No selector (1/0). If I have it "required" then it must have a 1 (Yes) value. If it has a 0 (No) value, it treats it as if it wasn't set.
Now, what I need is a third state. I need to know if they have not selected Yes or No, I want to require that they select one of them, and if they haven't, then I would give an error message about it being required. Now, normally I would use the NULL value to do this, but I'm not sure how this works in PHPMaker. Do I need to set the field with ENUM and 3 values? Perhaps 0,1,2 where 0 (default) would be "not selected" and then 1=Yes and 2=No?
