I use excel for my checkbook register and I have a budget that "runs" beside
it to keep a monthly track of everything in the same worksheet. I want to
write a formula that would take, for instance, my gasoline purchases from the
checkbook, then place and continue to add up the monthly gasoline purchases
in the budget column. I know very little about formulas. Right now, I
manually add up all the rows that say Gas for the month and place them into
the budget line. I appreciate your assistance.
