The problem is the first time your for loop runs it will return to the dtml and will not run anymore. Rather build up a list, or list of objects inside your method and then return. Dtml-in needs to see a list. -- Andy McKay, Developer.

I get a little mixed up) of my class. Here is the method, def list_messages(self): lr = open(self.user_dir+'/msg_list', 'r') spl = re.compile('\s\|\s') for msg_line in lr.readline(): num_from_sub = [] num_from_sub = spl.split(msg_line, 2) print num_from_sub self.msgnum = num_from_sub[0] self.msgfrom = 'This is from UNKNOWN' self.msgsub = 'My special subject' return self.msgnum, self.msgfrom, self.msgsub And here is an extract from the dtml file that is supposed to display the output, <dtml-in list_messages> <tr> <td><a href="/spool/&dtml-user;/get_message?&dtml-msgnum;">&dtml-msgfrom;</a></td> <td><a href="/spool/&dtml-user;/get_message?&dtml-msgnum;">&dtml-msgsub;</a></td> </tr> </dtml-in> However, this does not produce the desired effect. I don't know if it is obvious from what I've written, but basically, the three variables (self.msgnum, self.msgfrom and self.msgsub) are supposed to be inserted into the appropriate place in the table, and then the 'for' statement re-executed (producing different values for the variables) with the subsequent values being inserted into the next line of the table etc... until there are no more lines to be read from lr. I'm not sure if that is clear or not, sorry. Obviously, this does not work as the dtml-in simply iterates over each of the returned variables (instead of over the for statement). I can't seem to make it do what I want. Does anyone have any ideas? Much obliged if you do. Cheers tim
