Pivot table formula help

[matt45]

Hi,

I'm not sure how to put a queries per customer field in my pivot table. I have stripped down the pivot to a basic form which explains the problem. I need a no of queries per customer field which is basically the type of query/divided by the no of unique customers who logged that query.

I'd rather have the field calculated from within the pivot table but if needs must then I can add an extra column field in the source data. I just can't seem to think how to do it. Can you anybody help, It seems as if I need a countif with a match or it;

Thanks in advance

SOURCE DATA
customer query
a ltd failed machine

b ltd payment query
b ltd failed machine
c ltd payment query
f ltd failed machine
e ltd upgrade query
sa ltd upgrade query
q ltd failed machine
dfasdf ltd failed machine
b ltd upgrade query
c ltd failed machine
b ltd upgrade query
e ltd failed machine
