the number of radio buttons on a form, with the same name can be counted and checked to see if they are selected or not, starting from 0 to however many you have. the easiest way I have found to do this type of thing is to write a quick function to check which one is selected, you could extend it to check to see that one of them has actually been selected, but I dont want to do all the work for you.
simple function code
[code]
function genderCheck()
{
if (MyForm.gender[0].checked]){
var returnval = "Male";
}
else
{
var returnval = "Female"
}
return returnval
}
[/code]
the in the onsubmit part you could put something like this
[code]
onsubmit="var gender = genderCheck()"
[/code]
then pass the variable in your onclick function.
