Mozilla form submit problem

I have a problem,

I am trying to use the following vbscript to automatically submit a form. It works in IE but not in Mozilla. Does anyone have any suggestions on how to make this work?

<form name="frmUserCode" id="frmUserCode" method="POST" action="http://www.mysite.com/login.asp">
<input type="hidden" name="UCD" id="UCD" value="<% =str_UserCode % ">
</form>

<script type="text/vbscript" language="vbscript">
<!--
Document.GetElementByID("frmUserCode").Submit()
-->
</script>

Hmm, vbscript in anything other than IE probably won't work. Why not just use JavaScript?

I just got finished trying a javascript version of this and it behaved the same as with vbscript. Worked great in IE and didn't using Mozilla firefox.

I'm stumped! Any other suggestions.

Oh the joys of free enterprise with no standards...

I found the problem;

S vs. s in submit. Submit (bad). submit (good) in Mozilla firefox.

S vs. s in submit. Submit (good). submit (good) in IE.

document.frmSearch.submit();
