[RESOLVED] stupid javascript form.submit() problem

[Sibby]

ok, I have a link calling a javascript function

<a href=updateuser.aspx?id=123 onclick=submitAction(10)>save</a>

then I have a function defined that changes a value of a hidden form element

<script language="javascript">
   function submitAction(val) {
       document.myform.action.value = val;
       document.myform.submit();
   }
</script>

pretty damn simple so far right.....ok, well the link is clicked, in the Page_Load sub, I check the value of request.form("action") and attempt to take the appropriate action. When I check it the value is equal to NOTHING, which means the form never got submitted!! Now here's the kicker....when I put a meaningless alert box (see below) it works just fine!!?!?

   function submitAction(val) {
       document.myform.action.value = val;
       document.myform.submit();
       alert('garbage');
   }

I am at my wits end....can someone see what stupid thing I am doing wrong?
