[Zope] redirection from within forms with submit button

Gosh, you're harsh. I'll try.

Why the instant redirection?

I want to make the redirection conditional on clicking the submit
button.

Why _does_ it work as I'd like it to when in a separate form (you don't
have to read this;)?
The following produces an almost empty webpage with just a submit button. The
required action is only undertaken when the submit button is pressed:


<form method="post" action="">
<input type="submit" name="x" value="&gt;&nbsp;">
<dtml-if x>
<dtml-call "REQUEST.set('datum', _.str('1796/03/11'))">
<dtml-call "REQUEST.set('teller', 5)">
<input type="hidden" name="" value="<dtml-call
"RESPONSE.redirect('toondecr2?datum=%s&teller=%s' %
(datum,teller))">">
</dtml-if>
</form>
