[Zope] Printing data from a external python method.

Hello, I'm creating a smart forms type product, similar to Smarter Forms. However, smarter forms, while a good product, is not as user friendly or as smooth running as we would like. What I am doing is creating a Index, which calls the form, which once completed posts to the external pythod method formchecker. However, once formchecker checks to see that all the fields were filled out, how can I use the EPM (external python method to print out the data on a dtml method? Thank you for your input, Jesse.
