OK, Sorry, it looks like I pasted over the original post, so...<> I need to read in & comput totals & % of totals for about half of the columns. Trying to keep it simple as in, no external database. It's in Access now & it is real nice.

The data looks like this, representing customer counts & sales in 15 min incr. I need totals & percentages for each day, by section (cols 3,4,5/6,7,8, etc).

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
