Count If Help Please

[cware]

My data is arranged as:
a b c d .......
aa8 ATWIL HOM 45.87 ...
aa8 ATWIL AUT 34.54 ...
aa8 ATWIL DFW 26.75 ...
bb9 BBQRE PKG 222.76 ...


I have already been able to sum the d column by column A in sheet 2. Now I
want to count the different codes in column B by column A. The key is I
don't want to count everything, but how many different codes there are in
column B for a particular code in column A.

All help is greatly appreciated.

Thanks

Cathy

use the count if function with the match function:

=SUM(IF(FREQUENCY(MATCH(B2:B10,B2:B10,0),MATCH(B2:B10,B2:B10,0))>0,1))
this example must be entered as array formulas (array formula: A formula
that performs multiple calculations on one or more sets of values, and then
returns either a single result or multiple results. Array formulas are
enclosed between braces { } and are entered by pressing CTRL+SHIFT+ENTER.).
Select each cell that contains a formula, press F2, and then press
CTRL+SHIFT+ENTER.

I'm going to have to figure out the array thing because on first couple of
tries, this is not working for me. I'll try again later this week...thanks
