Python with Modelbuilder to create parameter inputs

Discussion created by kear1384 on Aug 8, 2013
I have two files I need to input into a model that I would like to be able to run over many folders.  The path of the second folder can be parsed from the first parameter using a python script.  How do I use this script within modlebuilder to create the input for the second parameter.

If I can figure out how to create the new path there is no reason for the second input to continue to be a parameter, this would be ideal.

To avoid a double post I am going to wait to post it to the python forum.
