Problem:

that is, if I have a html having some form variables and a submit
button. I click on the submit button. it should call some 
script..right?
My question is how to pass values from one script to another. how is
this done in Zope?

Solution:

It's simple there :-)

place the following code as a DTML-document with name "form_doc" in 
some folder.

<dtml-var standard_html_header>
<h2>A small form example</h2>
<p>
Ask a simple question here and call a DTML method which shows the 
answer.
</p>

<form action="show_res">
   <input name="tval" type="text" maxlength="20" width="20">
   <input type="submit" value="send">
</form>

<dtml-var standard_html_footer>

And the following in a DTML-method with name show_res.

<dtml-var standard_html_header>
<h2>Shows the result from the form_doc</h2>
<p>
The value of the form variable <tt>tval</tt> is <br>
<dtml-var tval>
</p>
<dtml-var standard_html_footer>

So the form values become members of the namespace of the called
method. There is a huge amount of documentation in the howtos and the
guides at www.zope.org or zdp.zope.org
