I have a report that lists the following columns:

Month Port# Name
April 123 Smith
April 123 Smith
April 234 Smith
April 345 Taylor
April 456 Taylor
May 567 Cox

I need a summary report from this that counts for each month and name how
many occurences. However, if the port# field is the same it counts it once.
So for April, Smith would have 2, Taylor would have 2. I tried to use a
PivotTable, but can't figure out how to not get it to count 123 twice. Any
suggestions would be greatly appreciated. Thanks!
