this was covered not long ago on one of these lists.

Try

if(document.form1.radio1.value == null) {
	//error stuff
}

Subject: Form validation




I am having a problem with validating form radio buttons. I can validate the
text boxes just fine.
How do I test for a radio button being checked? I have a form that has
several
text boxes
(name, address, phone number, city, state, zip), a question with 5 radion
buttons, another question
with 8 radion buttons, another question with 2 radion buttons, one submit
button
at the bottom of it all.
The text boxes are validated like this -

<script LANGUAGE="JAVASCRIPT">

<!--
function Verify()
{
  var Dealer = document.form1.Dealer.value;
  var DateInstalled = document.form1.DateInstalled.value;
  var Owner = document.form1.Owner.value;
  var Address1 = document.form1.Address1.value;
  //if (Question_Type == true)
     {
                if (Dealer == "")
                {
                alert('You have not specified the name of the Simrad Dealer
you
bought your product from.')
                return false
                }
                if (DateInstalled == "")
     {
                alert('You have not provided the date the product was
installed.')
                return false
                }
                if (Owner == "")
     {
                alert('You have not provided your name.')
                return false
                }
                if (Address1 == "")
     {
                alert('You have not provided your address.')
                return false
                }
    //}
}
//-->

</script>

And so on for all text boxes. I haven't figured out how to validate the
radion
buttons. I have seen
many web sites with info about  this but they have a submit button just for
the
radion buttons and
no text boxes mixed into the form. The above code is a piece of the whole
warranty registration
form for my company web site.
Can someone enlighten me? I'd like to just continue the same function as
above
to include the
radio buttons, if possible.
