[zope] newbie question : content_type

hi ! i try vainly to get the value of the "content_type" of a browser result and to affect it to a <dtml-var content_type> variable, in order to use and display it automatically in an other field "format" of a same form. i tried a number of options without making it work. can someone help me please ? r. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
