Sumproduct #N/A elminate?

[na]

I am using the following forumla:

=SUMPRODUCT(--(Sheet2!$D$2:$D$396>DATE(2004,6,15)),--(Sheet2!$D$2:$D$396<=DATE(2004,7,15)),Sheet2!$G$2:$G$396)+SUMPRODUCT(--(Sheet2!$K$2:$K$396>DATE(2004,6,15)),--(Sheet2!$K$2:$K$396<=DATE(2004,7,15)),Sheet2!$N$2:$N$396)

The question is: How do I omit cells within the range that have #N/A
(because data hasn't been entered in that cell to make the function work)?

Thanks

Hi
easiest way would be to change the formulas which creates the #NA. what
formula are you using in these cells

In the first sumproduct Column G has the following:
=E40*(VLOOKUP(F40,Airfare,2,FALSE))

in the second sum product columan N has: =VLOOKUP(M2,Airfare,3,False)

In the first sumproduct Column G has the following:
=E40*(VLOOKUP(F40,Airfare,2,FALSE))

in the second sum product columan N has
=VLOOKUP(M2,Airfare,3,False)...

If Airfare is sorted on its first column, use the faster:

=E40*IF(VLOOKUP(F40,Airfare,1,1)=F40,VLOOKUP(F40,Airfare,2,1),0)

Otherwise, you have to resort to costly...

=E40*IF(ISNA(VLOOKUP(F40,Airfare,2,FALSE)),0,VLOOKUP(F40,Airfare,2,FALSE)

Thanks - the second one worked for me!

If Airfare is sorted on its first column, use the faster:

=E40*IF(VLOOKUP(F40,Airfare,1,1)=F40,VLOOKUP(F40,Airfare,2,1),0)

Otherwise, you have to resort to costly...

=E40*IF(ISNA(VLOOKUP(F40,Airfare,2,FALSE)),0,VLOOKUP(F40,Airfare,2,FALSE))
