var impressions;

Thanks for any input!

Re: Proc Compare Question

First make sure that the two sets are sorted the same.

You may also want to set a FUZZ value of something like 0.000001.
I've had lots of cases comparing aggregated data back to an original data set where the differences were in the 1E-13 range and PROC COMPARE will set tell you they are all different. So either FUZZ or round values may help.
