calling JS function from a hyperlink

how do i call ajavscript fucntion from my hyprlink

VB Code:

<script language="JavaScript">
function checker(whichform){
var agree=confirm("Are you sure you wish to continue? This\nwill send an email to all Sales Managers!");
if (agree){
    document.whichform.submit();
}
}
</script>

ive manages to call this using a hyperlink:

VB Code:

<a href="javascript:checker('initial');"><font size="2" face="Verdana">Initial Request</font></a>

and i have set up the form to be submited at the bottom of the page

VB Code:

<form action="orion_s004.asp" method="post" name="initial" target="_self">
   <input type="hidden" name="F_PROFILE" value="<%response.write V_PROFILE%>">
   <input type="hidden" name="F_ACCESS" value="<%response.write V_ACCESS%>">
</form>

this works except its trying to submit a fortm caled whichform, when the whichform is a variable which should read 'initial'. I can send the form nuimber up and do it that way but id like to know why this deosnt work

try:

Code:

---

document.forms(whichform).submit();

---
