[Zope] DTML to ZPT code question

[Allen Schmidt]

Excellent!

Thanks Paul! I will give that a shot. Looks logical enough! :)

Our entire Zope life has been lived in DTML. Never a reason to switch. Others have done more with py scripts but now I am venturing into page templates more and the absolute need to do more in py scripts. TAL is slick but I still stumble on old DTML embedded 'logic' that I will have to move out to py and then call from tal.

Thanks again

Allen
