"I'm going nuts -- word vector frequency by category"

Processing documents from files, I categorize each document by which folder its coming from.  When I run the process requesting a word list result, I get a great word list table showing all the words from my process, the "Total Occurrences" and the "Document Occurences" as columns in the table.  Also included as columns in the table are each of my categories.  But all the cells for each of the categories shows 0, rather than what I want, which is the total occurences of the word in the category.  I'm sure I'm missing a simple operator to obtain this result but can't figure it out.  Any help would be appreciated.

Thanks.
Andy
