form validation problem...

hi, can someone tell me why this code isn't working, thanks.

i'm trying to get a hidden div to apear when there's no text entered in a name field,

document.getElementById(noName).style.visibility = "visible";

here's the code,

Expand|Select|Wrap|Line Numbers
  1. <SCRIPT LANGUAGE="JavaScript">
  2.     <!-- Hide code from non-js browsers
  3.     function validateForm()
  4.     {
  5.     formObj = document.formCard;
  6.     if ((formObj.name.value == "") ) {
  7.         document.getElementById(noName).style.visibility = "visible";
  8.         return false;
  9.     }
  10.     else
  11.         return true;
  12.     }
  13.     // end hiding -->
  14. </SCRIPT>
and the html

Expand|Select|Wrap|Line Numbers
  1.  
  2. <form id="formCard" name="formCard" method="post" action="" onSubmit="return validateForm()">
  3.             Name:<div id="noName">Please fill out your name</div>
  4.             <br />
  5.             <input name="name" type="text" id="name" size="30" />
  6.  
  7.           <input type="submit" name="Submit" value="Submit" />
  8.           </form>
