You will have to be much more specific.  Including snippets of code and the 
exact error message are a must.

However, it is much more likely that you have a cgi problem, not a ReportLab 
problemn.  We might want to redirect this to comp.lang.python.

The cgi.py module can be a bit picky.  Your capitalization must match 
exactly; if the form has:
   <input type=text name=MyText>
then you must use
  q = cgi.FieldStorage()
  s = q['MyText'].value

Also note that if you do not fill in a field, the field name will not appear 
in the FieldStorage object at all.  That's a common error.  Fortunately, it's 
easy to check for that:

  if q.has_key('MyText'):
    s = q['MyText'].value
    s = None
