Master Guru's, hello. Is there a shorter formula to replace this one, which counts the number of instances a combination of text appears in adjacent columns (in other words, the word "Car" appears in column C and the word "Accident" appears in column D.

I'm thinking I could cut this down if I had a more efficient way to factor in an infinite range (in other words $C19:C+Infinity) - as right now I'm using offset/max/counta. Is there a better way? Thank you.

=SUMPRODUCT((Report!$C$19:OFFSET(Report!$C$19,MAX(COUNTA(Report!C:C)),0)=Backend!P2)*(Report!$D$19:OFFSET(Report!$D$19,MAX(COUNTA(Report!D:D)),0)=Backend!Q2))

Can you name the ranges and then just use those names instead of cell references?

Hi brianCLong:

How about using the DCOUNTA function ... as illustrated in the following simple example:

1] If you are on Excel 2003 or beyond, convert the current data area in C:D into a list by means of Data|List|Create List then simply invoke:

=SUMPRODUCT(--(Report!CurrentCrange=Backend!P2),--(Report!CurrentDrange=Backend!Q2))

The formula will adjust automatically to any change in C:D.

Otherwise:

2]

Define Dsize as:

=MATCH(REPT("z",255),Report!$C:$C)-ROW(Report!$C$19)+1

Then invoke:

=SUMPRODUCT(--(OFFSET(Report!$C$19,0,0,Dsize)=Backend!P2),--(OFFSET(Report!$D$19,0,0,Dsize)=Backend!Q2))

3] Define:

Dsize as stipulated above

Crange as:

=OFFSET(Report!$C$19,0,0,Dsize)

Drange as:

=Offset(Report!$D$19,0,0,Dsize)

Then invoke:

=SUMPRODUCT(--(Crange=Backend!P2),--(Drange=Backend!Q2))

4] Invoke a formula with DCOUNTA as suggested...
