I currently use the following to count the number of occurrences that time
shows on my report. This is a great formula.

=SUMPRODUCT((AB3:AB10000=TIME(6,45,0))*(AB3:AB100 00<=TIME(7,29,59)))

What I need in its place is a formula that counts the occurrences of time
only if the cell next to the time shows a 1.

example:

A B
7:54:34 2
8:28:40 1
8:50:16 2
9:32:07 2
10:10:36 2
10:11:02 1

I only want to count a time period only if there is a number one in the next
cell.

Thanks for the help
