This might be a simple question, but I haven't been able to find a straightforward answer.

I'm working on an ArcGIS (9.3) Python script. One of the inputs is a list of features. For each feature, I need to select a corresponding field. Setting the parameter to MultiValue gives a nice table in the UI for all the features being processed. How do I add another column to the MultiValue table to select a field for each feature?

EDIT (I can't answer my own question for 8 hours?): ESRI's Answer from the ArcGIS forum: "Unfortunately, the solution for this was implemented just recently for 10.1 with ValueTable inputs for script tools. You will need to have two multivalue parameters with some custom validation to make this work for 9.3.1."

Jason Scheirer had something to say 4 months later (watch cross+post). –  r.pankevicius Feb 8 '12 at 23:04

If it is the generation of multivalue choise list you are interested in - I've seen this Esri blog post recently, it might be helpful.
