Formula in Pivot Table
 

Hi,
When I select Calculated Item in Pivot table formula I received an error
message saying Multiple data field on the same field are not supported when a
Pivot table report has calculated Item.
In my Data table I have one column with a formula selecting is this a
SalesA,B,Refusal or Pending. and show: A,B, R, P

What I need to do is quite simple:
I needs to add A and B together in the Pivot Table only
My Fields "Status" Show
By Salesman
SalesA, SalesB, Refusal, Pending. Then I have a total for all
For each Data Field I have Sum # and % of the total
Example:
A B R P
Total#
Stat# Stat% Stat# Stat% Stat# Stat% Stat# Stat%
2 8.70% 1 4.35% 1 4.35% 19 82.61% 23
100%


Need 1 Column in Pivot table saying:
Total A+B# Total A+B%
2 8.70%
Looks simple, however I can't figure the way to do this.
Thanks for your help.
