How to get pivot to ignore blanks when drilling down

Hi all,

First post so bear with me. I am realling hoping to learn what type of lingo you guys/gals use on this forum so i will be able to search what i am looking for.

On to my issue:

Let me simplfy this as much as possible lets assume i have this data:
1=indicator variable for yes
--------------Blonde Hair -------- Blue Eyes---------Over five feet tall
Bob-------------1------------------0------------------------1
Frank-----------0-------------------0-----------------------0
Joe-------------1-------------------1-----------------------1
Sue------------0-------------------1-----------------------0
Beth ----------1-------------------0-----------------------0

I can make the pivot table show something like so
Blonde Hair----------3
Blue Eyes-----------2
Over five feet tall---2

Now my issue when i double click the 3 to see who has blonde hair it opens up all 5 people. How do i get the pivot table to ignore blanks or zeros (which ever i end up doing)

Let me know how i can improve my posts i tried to simplfy this as much as possible
