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))

Does the VLOOKUP table have to be sorted?
No! when you are using an exact match, the VLOOKUP table can be in any order. Best-selling items at the top is actually the best.
Sort by date Sort by votes
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:

Click to expand...

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...
