Form Validation Input Text and Checkboxes

The form and javascript below works well for the input text boxes, but I cannot seem to integrate the validation for the one, single checkbox.

Form code (minus some guts):

[CODE]<form name=”msgform” method=”post” action=”rma.php” enctype=”multipart/form-data” onsubmit=”return validate(msgform);” value=”” />
<div id=”SignUp”>
<table width=”560″ cellspacing=”0″ cellpadding=”5″>

Javascript Validation

[CODE]<script language=”javascript”>
function validate(frm) {
var inputFields = new Array(“First Name” ,”Last Name” ,”Company” ,”Address1″ ,”City” ,”Zip” ,”Country” ,”Phone” ,”formmail_mail_email” ,”Return Quantity 1″ ,”Purchase Order 1″ ,”Part Number 1″ ,”Reason for Return 1″);
var counter;
var name;
var msg = “Please complete the following fields:n”;
var badFields = “”;
for (counter = 0; counter < inputFields.length; counter++) {
name = inputFields[counter];
if (frm.elements[name].value.length == 0) {
if (name == “formmail_mail_email”) {
badFields = badFields + ” – Email n”;
} else {
badFields = badFields + ” – ” + name + “n”;
}
}
}
if (badFields.length != 0) {
alert(msg + badFields);
return false;
}
if (frm.formmail_mail_email.value.length > 0) {
return emailCheck(frm.formmail_mail_email.value);
} else {
return true;
}
if (frm.terms.checked) {
return true;
} else {
alert(‘You must agree to the Terms and Conditions’);
return false;
}

}

function emailCheck(emailStr) {
var emailPat=/^(.+)@(.+)$/;
var specialChars=”\(\)<>@,;:\\\”\.\[\]”;
var validChars=”[^\s” + specialChars + “]”;

var userPat=new RegExp(“^” + word + “(\.” + word + “)*$”);

alert(“The address must end in a three-letter domain, or two letter country.”);
return false;
}

if (len<2) {
var errStr=”This address is missing a hostname!”;
alert(errStr);
return false;
}

return true;
}
</script>
[/CODE]

Any idea?

Thanks
