Hi

I have a spreadsheet where a formulae
'=SUMPRODUCT((A$2:A$11="S")*(A$2:A$11<A$3:A$12)) ' was initially set to
count separate instances of "S"in a Column A

S

SD

SD
SN

S



This works fine but I need to extend the formula so it counts the number of
instances of S, SD or SN.

In the above example there are four seperate instances but the formula I
have created '
=SUMPRODUCT((A$2:A$11="S")*(A$2:A$11<A$3:A$12))+S UMPRODUCT((A$2:A$11="SD")*
(A$2:A$11<A$3:A$12))+SUMPRODUCT((A$2:A$11="SN")*( A$2:A$11<A$3:A$12))
'counts five because although the SD and SN follow each other it counts them
as seperate.
I need it to count the SD & SN together as one instance.

Hope I have explained OK - any suggestions welcome.

Regards

Paul
