[Zope] Mailform & Sendmail

Hi guys, I want to create a sendmail-Method which works with several forms. For that I want to list the variables and their values independent from each form. <dtml-var "REQUEST.form"> works, but the output is: {'comments': 'my comment', 'name': 'my name'}. What I would like to see is: comments: my comment name: my name' but I don't want to create for each form a sendmail-Method which includes: comment: <dtml-var comments> Name: <dtml-var name> My idea was something like <dtml-in "REQUEST.form"> <dtml-var name>: <dtml-var value> </dtml-in> but REQUEST.form isn't a sequence!? I guess this is an easy question. Thank you in advance, Tapio
