Form function

I have a form that dumps the data the users types into an Access DB. In the
form there are two radio buttons, the way the form is coded now only the
results from one of the buttons is getting entered into the DB. How do I fix
this?? Below is the code for the function. I think that I need to add another
value for the radio buttons, adn adjust/add a function, but I'm not sure.
Advice would be much appreciated. Thanks! Function BinaryFixup(theString) if
theString = 'on' or theString = '1' or theString = 'true' or theString = 1 then
BinaryFixup= 1 else BinaryFixup= 0 end if End Function
