Maybe this...

=COUNTIF('Data (2)'!$Y$2:$Y$1508,"=-15")-COUNTIF('Data
(2)'!$Y$2:$Y$1508,"15")

I imagine this is a simple question, but I would like to do something like
the formula below, but I would like to do it for a range within 15 minutes
(+15 or -15 of 0).

=COUNTIF('Data (2)'!$Y$2:$Y$1508,"30")

Thanks
