I have a form with radio buttons which lists different ways for a person to be contacted. Once a radio button is clicked, it checks to see whether the information exists. If it doesn't it returns a message requesting the information. Now this is all fine.

My problem: How can I force the radio button to be 'un-selected' if there is no information for that contact?

Heres the section of code affected:

function CheckContact(contact) //contact is the name of the
//radio buttons
{
for (var index = 0; index < contact.length; index++)
{
if (contact[index].checked)
{
var answer = contact[index];
break;
}
}
if (answer.value == "email") //only testing the email
{ //for now
email = document.getElementById("email");
if (email.value == "") //if empty
{
alert ("You have not entered an email address for us\n" +
"to contact you by.");
email.focus();

//something belongs here to uncheck my radio
//button

return false;
}
}
if (answer == "postal")
{
alert ("postal");
}
if (answer == "phone")
{
alert ("phone");
}

}

I would really appreciate the help.

You can use something like this to uncheck radio buttons. This will uncheck all of the radio buttons in the form that you specify. If you only want to do a few of them, you'll have to modify it a bit...

<script type="text/javascript">
function uncheck() {
for (i=0; i<document.formname.elements.length; i++) {
if (document.formname.elements[i].type == "radio") {
document.formname.elements[i].checked = "";
}
}
}
</script>
</head>
<body>
<form name="formname">
<p><input type="radio" name="rad1">
<input type="radio" name="rad2">
<input type="radio" name="rad3"><br>
<button type="button" onclick="uncheck();">Uncheck</button></p>
</form>
