Counting custom fields in PHP

[pshadow]

this was great. I tried to do the same thing and it works perfect. thanks.

I'm wondering how to make 2 edits though:
1. exclude counting and displaying the empty fields. currently shows 500 blank.
2. not really related but, it displays whats in the field5 fine, how do I get the original field number from the select menus of the custom field? i.e. the ID that is used in the search => getall&field5=3 rather than getall&field5=orange
