I am currently working on a project that I can't figure out the last few
details. This is similar to what I have:
Program: (followed by validated list of programs as a dropdown)
Features: (followed by validated list of features as a dropdown)

Table in another tab:
Program Feature
Word Table of Contents
Excel Pivot Table
Both Save
Both Print

I would like to limit the Features validation to only display features that
are in the program the user chose (i.e., If they chose Word as the program,
it should only show Table of Contents, Save, and Print in the dropdown). Any
ideas on this?
