That seems to be a lot of code to accomplish such a small thing..
Code:
function chkform(form) {
if(form.usr[0].checked!=true) {
alert("Please select Yes or No:");
form.usr[0].focus();
return false;
}
}
Just put the [0] part on the name of the radio element in the code.. it just refers to the first radio element with the "usr" name.. if you want to check the second, it would me [1]..
