[Zope] Evaluating Output of Scripts as HTML in DTML Pages

BTW perhaps there's a better way to achieve this that I haven't considered,
so please let me know. 

As for the (as yet non-existent) script I mention below -
myParseDTML("3.4","Cheques in System", "RA3_4","NRA3_4", "TOT3_4")

I was thinking I'd store a list (of lists) in the directory, where one of
the elements of the list would be the above.

Can I use an external method to generate the html? How?

Hello all,

I'm not even sure where I can look for the answer to this problem.

I have a SQL table with a large number of variables. I have a data entry
form that uses the following logic about 30 times on a page - 
<dtml-let a=RA3_4 b=NRA3_4 t=TOT3_4>
  <td />
  <td class="row-label">
  <dtml-if "a+b==t"><span>
  <dtml-else><span class="error">
  Cheques in System</span></td>
  <td><input type="text" dir="rtl" name="RA3_4"  value="<dtml-var a>"
size="12" maxlength="12" /></td>
  <td><input type="text" dir="rtl" name="NRA3_4" value="<dtml-var b>"
size="12" maxlength="12" /></td>
  <td><input type="text" dir="rtl" name="TOT3_4" value="<dtml-var t>"
size="12" maxlength="12" /></td>

What I'd like to be able to do is create a Python script that returns the
above, AND I need the DTML document to recognise it as part of the code. The
above code snippet would be generated by a script, called as -

myParseDTML("3.4","Cheques in System", "RA3_4","NRA3_4", "TOT3_4")

This script would return the above code. My problem is, I can generate the
above code, but it's not evaluated within a DTML Method.

As a simple example, I have the following python script -
""" script name - testScript """
<dtml-var standard_html_header>
<dtml-var standard_html_footer>
return text

How do I get the return value of this script to actually display the above
items in a DTML Method? 

(I hope I've explained this well)

Thanks in advance. Any help will be greatly appreciated.
