Hello,

I'm using Excel 2007 to keep track of attendance for classes held on
different days. I'm would like to create a formula that SUMS up the number
of attendees for each day. Is there a function that would SUM values for each
day it encounters? (example: Sum up all the data for each time you see 8/1/08
and then Sum all the data for each time you see 8/2/08).

Thanks,
