Validation issue

Validation issue

Hi Folks,

I am new to JQuery and have used it for an application form. Unfortunately, the validation is not working as it should. I'm not sure exactly where I might be going wrong. The form still "submits" even though the validation has picked up on blank fields. I have pasted the coded below:

**** START OF CODE ****

<script type="text/javascript">

$(function(){
// Grab each form element
$("label[title]").each(function(){
$(this).append("<div class=\"infopop\">");
titletext = $(this).attr("title");
$(this).removeAttr("title");
$(".infopop",this).css({opacity:0}).html(titletext);
// Disable Submit button
$("#submit").attr("disabled",true);
$("#terms").click(function(){
this.checked = false;
});

$("#terms").click(function(){
if (this.checked = true) {
$("#submit").attr("disabled",false);
}
else {
$("#submit").attr("disabled",true); }
});
$("input,textarea",this).focus(function(){
// Mouseover
doFocus(this);
}).blur(function(){
// MouseOut
doBlur(this);
});
});
});

$(function submit(){
$('#formS').submit(function(){
$('input, textarea').each(function(n,element){
if ($(element).val()=='') {
alert('Please complete the field "'+element.id+'". Thank you.');
document.formS.name.focus();
return false;
}
return true;
});
});
});


function doFocus(obj) {
$(obj).addClass("active").parents("label").addClass("active").find(".infopop").animate({opacity:1,left:492},500);
}

function doBlur(obj) {
if (validate(obj)) {
isGood(obj);
}
}

function reportErr(obj, message) {
$(obj).addClass("error").parents("label").removeClass("isgood").addClass("required").addClass("error").find(".infopop").html(message).addClass("errorpop").animate({opacity:1,left:492},500);
}

function isGood(obj) {
$(obj).removeClass("error").removeClass("active").parents("label").addClass("isgood").removeClass("error").removeClass("active").find(".infopop").removeClass("errorpop").animate({opacity:0,left:513},500);
}

function validate(obj) {

// Extend jQuery object to include Regular expression masks assigned to properties
