it doesn't seem to work. Can anybody shed some more light on this

it's not working.<BR><BR>Am I forgetting to put parameteres or some other
newbie mistake like that?<BR><BR>Thanks in advance and thanks again

[Zope] Python Scripts and HTML Forms</DIV>
<DIV><BR></DIV>Dear Trusted Zope Zealots,<BR><BR>This subject was a bit
too broad to do a google search on, because I've tried and the lack of
relevancy was astounding.<BR><BR>I've probably been committing a cardinal
sin in DTML, but I couldn't figure any other work around. <BR><BR>I have
an HTML form in a DTML Document say:<BR><BR><form
action="process_this_form" method="post"<BR><BR>Name:<input type="text"
name:"first_name"><BR><BR></form> <BR><BR>I want to use
"first_name" in a python script, but what I've been doing is setting it in
the process_this_form, which is a DTML method:<BR><BR>DTML Method,
process_this_form:<BR><dtml-call "REQUEST.SESSION.set ('firstName',
first_name)><BR><dtml-call
"this_is_a_python_script()"><BR><BR>and in the Python Script,
this_is_a_python_script<BR>I use
REQUEST.SESSION.get('firstName')<BR><BR>What my question is, is there
anyway to directly access "first_name" from the form in the python script
without having to have to call the <dtml-call "
REQUEST.SESSION.set('firstName', first_name)> and then
REQUEST.SESSION.get('firstName') in the python script. Sort of a
sophomoric question, but any help would be appreciated. Thanks in
advance.<BR><BR>-Muk<BR></SPAN></DIV>
