I have a multi-sheet workbook in which I would like to autofill key cells.
Sheet 1 contains spec records that can be tagged for complexity: high,
medium, low. Sheet 2 contains the autofill cells.

My problem: I wish to use two combo boxes to filter the spec records by tag.
Combo Box 1 allows the user to select the appropriate complexity level.
Based on this selection, Combo Box 2 should populate with the filtered
records. Selecting a record in Combo Box 2, finally, should populate the
autofill cells with the appropriate information.

I attempted to use Tom Oglivy's code on "Filtered list for Combo Box
ListFillRange" response to populate Combo Box 2. It is not working and, as a
VBA newbie, I need additional assistance.
