Hi!

Assume on sheet2 you have:

A1 = Acft #
B1 = Name
C1 = Hours

A2:A11 = 1,2,3,4...10

In sheet2 C2 enter this formula and copy down to C11:

=SUMIF(Sheet1!A:A,A2,Sheet1!B:B)

This assumes that every time an acft flies you make a new entry on sheet1 in
a new row.

Hi all...a newbie here.

I'm okay with many Excel functions, but I don't go too deep: Can't do
macros, lookups, that sort of thing.

Here's my dilemma: Sheet-2 has a list of 10 aircraft, and the goal is
to accumulate the hours-flown for each aircraft...Column A is the
aircraft# (1-10), B is the aircraft name, C is the accumulated
hours-flown. Keeping it simple, let's say that A1=1, B1=Cessna, and
C1=26.5

Now, back to Sheet-1: Someone flew the Cessna for 2 hours...in A1 I'll
enter 1 for the aircraft#, and in B1 I'll enter "2" for the hours-flown.
Now Sheet-2 C1=28.5, or maybe some cell on Sheet-1, for all I care.

I can, of course, just go to Sheet 2, find the right column/cell and
update manually, but this is duplicated effort that leaves way too much
room for human error.

If anyone can help with this, it would be much appreciated...let me
know if you want a copy of the existing spreadsheet.

Thanks,
Garry )
