Re: [Zope] Newbies & variables

      Alright.  What does it return?
Based upon this:
...
...
...
return special_formats['structured-text'](_[page_body])
It should return the result of calling whatever method is returned by 
getting the 'structured-text' element of the special_formats dictionary 
with page_body as the only argument.  Whew!  Why don't you just do this:

myhome.html:

<dtml-var name="standard_html_header">
<dtml-let page_body="'stuff.stx'">
   <dtml-var name="dtml_wrapper">
</dtml-let>
<dtml-var name="standard_html_footer">

dtml_wrapper:

<dtml-if name="page_body">
   <dtml-if expr="page_body[-4:] == '.stx'">
     <dtml-var name="page_body" fmt="structured-text">
   <dtml-else>
     <dtml-var name="page_body">
   </dtml-if>
<dtml-else>
   <dtml-var name="default_page">
</dtml-if>

Am I making sense, or missing the point?  Alright, I admit it.  I really 
like DTML (though sometimes...)

Well, I added it as a parameter, and that fixed the immediate problem,
however it doesn't return myhome.stx as it should....curiouser and

Gary,
Is page_body listed as a Python Script parameter?  If not, try adding 
it.  If so, this could be significantly more complex.

In working thru the examples in the Zope Web Applications
book, it is

demonstrating the use of python scripts. I have the following code
elements:
myhome.html:
<dtml-let page_body="'myhome.stx'">
 <dtml-var standard_dtml_wrapper>
</dtml-let>
standard_dtml_wrapper:
<html>
  <head>
      <title><dtml-var title_or_id></title>
  </head>
  <body>
      <dtml-var banner>
      <dtml-call choose_page_body>
  </body>
</html>
And finally, choose_page_body (type script)
from Products.PythonScripts.standard import special_formats
if page_body :
 if page_body[-4] == ".stx" :
   return special_formats['structured-text'](_[page_body])
 else :
   return _[page_body]
else :
 return default_page
In thiscase, I also bound namespace=_
My problem is that when trying to view this, I get an error on 
page_body indicating that the python script knows nothing about it. 
Since this is all originating from within the <dtml-let> block, I 
thought it would carry thru. Since it isn't, how do I fix this?
