[Zope] redirection from within forms with submit button

Thanks

?? Irritated about my ignorance? Sure.

I want submit buttons because they are supposed to be more intuitively
recognisable for the user. Another reason is that I have a sort of
horizontal navigation bar which should be able to handle a couple of
redirections (page x images further, jump to a certain day) for which
i seem to need forms anyway.

Obviously I'm missing something (well, a lot). For instance, why does this work in a
separate method:
> <dtml-call "RESPONSE.redirect('toondecr?datum=%s&teller=%s' %
(datum,teller))">>

and not in the method toondecr2 (which is a clone of toondecr with the
submit form added)?

Why can i display the dtml-var's 'datum' and 'teller' in the submit
button:
<input type="submit" name="x" value="<dtml-var datum><dtml-var teller>">
and yet get this error when clicking the submit button:
Error Type: NameError
Error Value: global name 'datum' is not defined

Just can't figure why the variables ain't passed.

Ah well, thanks a lot for your efforts. Have a nice weekend.

Cheers, Dirk
