Trying to add new "required" field in PHP form

[Mr.Canuck]

I am trying to add another "required field" to my PHP form, but I'm not sure what I'm doing wrong. The form and "required fields" work fine, but I am now trying to make the "Select skill level which is an "input type="radio" as a required field, but it is not working. As you can see below, I just tried adding the new "required" field the same way as the other 4 were set up, but it is not working (I think I have to do something different because the new "required field" is a "radio" type and the rest are "text"). The relevant parts of the code are below. Any assistance would be appreciated

 

<script type="text/JavaScript">
function verify() {
var Skill = document.indiv_reg.skill.value;
var Fname = document.indiv_reg.name.value;
var Hphn = document.indiv_reg.home_num.value;
var Email = document.indiv_reg.email.value;
var Tname = document.indiv_reg.tname.value;

if ((Fname =="") || (Skill =="") || (Hphn =="") || (Email =="") || (Tname =="")) {
alert('Please Fill Out ALL Required Fields');
}
else {
document.indiv_reg.submit();
}
}
</script>

 

<?php
$url = "https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=6Y76L7TX6FVRW";
$sport = $_GET['sport'];
$league = $_GET['league'];
$visitor = $_GET['name'];
$skill = $_GET['skill'];
$tname = $_GET['tname'];
$tcap = $_GET['tcap'];
$homephn = $_GET['home_num'];
$cellphn = $_GET['cell_num'];
<?php

You're wanting to use php to accomplish this, since Javascript can't be relied upon as a validation method, right?

I would agree with that statement, but I just want to add the "radio button" field as a "required" selection within the existing code (just need a quick fix for this one)
