=SUMPRODUCT formula is counting the blank cells as well as zero's

[Guest]

Hello,

I am using the following to count a column of zero’s in a worksheet if the
zero’s occur during specific times.

=SUMPRODUCT(--(pathfinder_dump!G1:G10000>=TIME(1,0,0)),--(pathfinder_dump!G1:G10000<=TIME(1,29,59)),--(pathfinder_dump!I1:I10000=0))

The trouble is that the formula is counting the blank cells as well. Can
someone tell me how to modify so the formula only counts the zero’s?

Thanks

add this to your formula
1-ISBLANK(C1:C6)

=SUMPRODUCT(1-ISBLANK(C1:C6),--(pathfinder_dump!G1:G10000>=TIME(1,0,0)),--(pathfinder_dump!G1:G10000<=TIME(1,29,59)),--(pathfinder_dump!I1:I10000=0))

sorry, I didn't change the range in my last post.

=SUMPRODUCT(1-ISBLANK(pathfinder_dump!I1:I10000),--(pathfinder_dump!G1:G10000>=TIME(1,0,0)),--(pathfinder_dump!G1:G10000<=TIME(1,29,59)),--(pathfinder_dump!I1:I10000=0))
