multi dimensional pivot table question with call center call data

[WRSallee]

I have a data source which has 1 row per call. i have columns which have agent name, routing skill, and call disposition. I need each agent as a row with routing skill underneath. (no problem) Then I have the count of Calls for each skill and a subtotal (again, no problem). Here's the problem: I need an additional column which contains a certain disposition. When I filter the column for that disposition, the call counts are reduced. So basically I am trying to determine how many sales calls an agent took, by skill, (there are several sales skills by three brands) AND how many calls in each of those skills carry the sales disposition so I can calculate a close rate by skill by agent.
