Form.submit

hi, i have a form that looks somthing like this...

<form name=userInfo action="cgi-bin/userinfo.pl" method=post>

blah
blah
blah

<!-- now i have an optional link allowing the user to go to a different page to upload a picture-->

<a href="upload.htm" onclick=upload()>Upload a picture</a>

<!-- and the standard submit button -->
<input type=submit value=Go>

</form>

now, if the user decides to use the link to go to the upload page, i still want the form to be processed so they dont lose any info theyve already entered. here is what i tried...

<SCRIPT LANGUAGE=javascript>

function upload()
{ Forms.userInfo.submit; }

or

function upload()
{ Form.submit; }

or

function upload()
{ userInfo.submit; }

</JAVASCRIPT>

the link works and there are no javascript errors, however, the form is never processed by userinfo.pl

do i have the right idea?
any help would be appreciated.

thanks
