Someone to look over code and help me find error (simple newbie problem)

Hi.

I'm working on learning about cookies. I've got a very short sample script given to me in class and I found the same script in a Javascript book (I guess I figured out what the teacher's been reading).

When I open this script in IE, I get a Javascript error that 'userName is undefined' at line 23.

Here's a link to the page where you can try it out... www.detailsfree.com/cscd378/cookie.html

Here's the code:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Cookie</title>
<script language="Javascript" type="text/javascript">
  <!-- Hide script from older browers
  expireDate = new Date();
  expireDate.setMonth(expireDate.getMonth()+6);
	
  userName = "";
  if (document.cookie != "" {
    userName = document.cookie.split("=")[1];
  } // end if
	
  function setCookie() {
    userName = document.myForm.nameField.value;
    document.cookie = "userName=" + userName + "; expires=" + expireDate.toGMTString();
  } // end function
  //-->
</script>
</head>

<body bgcolor="#FFFFFF" onload="document.myForm.nameField.value = userName">
  <form name="myForm" action="#">
    <h1>Enter your name: <input type="text" name="nameField" onblur="setCookie()" /></h1>
  </form>
</body>
</html>

I'd appreciate any feedback on this. Thanks.

Found the error.

I had a missing right parenthesis ')'.
