    Reading Data From Cookie

    I have created a basic form in JavaScript that asks for user data, I then store that data in a cookie. What I need is if the user comes back to the page and fills in the same data I want to re-direct the user to another page stating that has already been entered. Right now I know I am able to read the cookie because I put in a test message on page load to show me the data. I just don't know how to compare the data in the cookie with the data entered and then re-direct if the data matches....

    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtmll/DTD/xhtmll-strict.dtd">
    <html>
    <head>
    <title>Kudler Fine Foods Customer Form</title>
    <style type="text/css">
    	body { font-family: "Trebuchet MS", Arial, Helvetica, sans-serif, serif}
    	h2 { font-size: 1.2em }
    </style>
    <script type=text/javascript>
    <!--HIDE FROM INCOMPATIBLE BROWSERS
    function checkForNumber(fieldValue) {
    		var numberCheck = isNaN(fieldValue);
    		if (numberCheck == true) {
    				window.alert("You must enter a numeric value!");
    				return false;
    		}
    	}
    function confirmPassword() {
    		if (document.forms[0].password.value !=
    				document.forms[0].password_confirm.value) {
    					window.alert("You did not enter the same password!");
    						document.forms[0].password.focus();
    					}
    		}
    function ensurePasswordConfirm () {
    		if (!document.forms[0].password_confirm.focus()) {
    				window.alert("You must confirm the password you entered!");
    			document.forms[0].password_confirm.focus();
    			}
    }
    function confirmSubmit() {
    		if (document.forms[0].name.value == "") {
    			window.alert("You must enter your name!!");
    			return false;
    		}
    		if (document.forms[0].address.value == "" 
    			|| document.forms[0].email_address.value == "")	{
    			window.alert("You must enter your address or email address!!");
    			return false;
    		}
    }
    function confirmReset () {
    		var resetForm = window.confirm("Are you sure you want to reset the form?");
    			if (resetForm == true)
    					return true;
    			return false;
    }
    function setCookie () {
    		var expiresDate = new Date();
    		expiresDate.setFullYear(expiresDate.getFullYear() + 1);
    		document.cookie = encodeURI ("name=" 
    			+ document.forms[0].name.value) + "; expires="
    			+ expiresDate.toUTCString ();
    		document.cookie = encodeURI ("address="
    			+ document.forms[0].address.value) + "; expires="
    			+ expiresDate.toUTCString ();
    	}
    function getCookie () {
    		var getData = decodeURI(document.cookie);
    		var data = getData.split("; ")
    		var name = data[0].split("=");
    		var address = data[1].split("=");
    		window.alert("Welcome " + name[1] + " Your address is " + address[1]);
    	}

    Don't want to duplicate the thread, so closing.
