[Zope-DB] changing from dtml-in

[D. Rick Anderson]

Ok. I think I figured it out. It looks like you have to stuff all that 
you want returned into a single string and then 'return' it. Here's what 
I came up with:

x = context.basicReport()
final = ''
if x:
 for result in x:
  final = final + str(result.accid) + '<br>\n'

return final

Thanks for the help,

Rick
