radio button/form information

How would I adjust this so that it registers either radio button value in the
database rather than just the first one? The code works, just doesn't dump the
all the information.... 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 Thanks!!
