Hey everyone,

I have collected some information from a SQL database and dumped them into an ACCESS table.

Now I want to report on this table and make some calculations.

This calculations is basically to figure out the change between the rows
the table looks like this:

RowNUM TimeRecords Contacts Logins Durations
1 1298 12 63 41
2 1300 15 72 42
3 1600 20 52 43

Now I want the change between rownum 1 and 2, and 2 and 3 and so forth?? How would I do that?

Any clues? Ideas? Thanks!!
