I use a spreadsheet to track machine issues, minutes, and dates for a group
of machines(D/S).
Sample source data:
D/S # Date Issue desc. Minutes
D/S1 1/1/2007 Issue A 5
D/S1 1/1/2007 Issue B 11
D/S2 1/1/2007 Issue A 6
D/S3 1/1/2007 Issue A 8
D/S1 1/2/2007 Issue A 5
D/S2 1/2/2007 Issue B 2
D/S3 1/2/2007 Issue C 3
D/S3 1/2/2007 Issue D 4

I can run a pivot on the data summing the minutes of each discrete issue
with a grouping by date. It is sorted to show top 3 Issues based on sum of
minutes. i.e.

Sum of Minutes Date
Issue desc. D/S # 1/1/2007 - 1/2/2007
Issue A D/S1 10
D/S2 6
D/S3 8
Issue B D/S1 11
D/S2 2
Issue C D/S3 3

What I want is a pivot with the same date grouping that will show me the
overall top 3 issues based on the discrete sum of minutes for each D/S. i.e.

Sum of Minutes Date
Issue desc. D/S # 1/1/2007 - 1/2/2007
Issue B D/S1 11
Issue A D/S1 10
Issue A D/S3 8

Any help on this would be greatly appreciated.
