here is the exact way i have done it...
you fill out the form how ever you need to make it.. the name of the form is name="nameOFform"
<form name="nameOFform" method="POST" action="https://testform.com/cgi-bin/form.cgi">
<input type="hidden" name="hellopage" value="">
<input type="hidden" name="reqtype" value="secure">
</form>
here is the example of a text link using the form to link to it
<a href="javascript
:document.nameOFform.submit()">thi s is a test</a>
make sure nameOFform is the same as the one above this should work perfect
