simple math sql - need help

Am humble...need help w/ basic sql since I don't write it often enough

Table has first 2 columns...need the SumPast4 column created in query showing these three columns... don't need to worry about the n/a example just trying to show that the sum is of the current and past three records...

thanks in advance

RE: simple math sql - need help

Hi there:

break on report;
compute sum of SumPast4 on report;
select "sequence rev", SumPast4
from "table name"
order by "sequence rev"

This should do it for you.
