Topic awaiting preservation: Form Validation Problem

Hi,
I am trying to validate a form, and am getting the error messages as needed, but it submits the form anyway.

Here is the Java:

function validate (form){

var returnValue = true;

var email = CSLavRequestForm.email.value;
var phone = CSLavRequestForm.phoneNumber.value;
var groupName = CSLavRequestForm.workshopName.value;

if (email.length < 6){
returnValue = false;
alert("Please Enter Valid email");
CSLavRequestForm.email.focus();
}
if (phone.length < 10){
returnValue = false;
alert("Please Enter Valid Phone Number");
CSLavRequestForm.phone.focus();
}
if (groupName.length < 3){
returnValue = false;
alert("Please Enter Valid Workshop/Region");
CSLavRequestForm.groupName.focus();
}

return returnValue;
}
</script>

and the form line in the html:

<form onsubmit="return validate(this);" action="/cgi-sys/formmail.pl" method="post" name="CSLavRequestForm" id="CSLavRequestForm" >


I am stuck! Benn working on this for way too long

Don't see any obvious mistake, have you looked if the error console of decent browsers has anything to say? Have you replayced return validate(this); with alert(validate(this)); just to check you do get false back?

so long,
