Linda,

If you put the activities in M1,N1,O1, etc., then in M2 add

=SUMPRODUCT(--($B$2:$B$5=M$1),($D$2:$D$5-$C$2:$C$5))*24*4

and copy across.

Below is the table that I'm using. (hope it posts this legible) The
formula I
need is that everything that is a 1 in Activity, will add the those 15/min
increments up in a separate cell; everthing that is a 2, etc. Again each
month will be different.

Date Activity Begin Time End Time "15/min. Increments"

1/1/08 1 7:00 15:00 32.00
1/1/08 2 15:00 17:00 8.00
1/1/08 1 17:00 17:30 2.00
1/1/08 8 17:30 17:55 1.67
0.00
0.00
0.00

Formula for this column

=(D2-C2+(D2<C2))*24/0.25

I couldn't make your formula work.

where B2:b200 is the times, C2:C200 is the categories, D2:D200 is the
amounts.

You can put the test values in cells and check against these, better in a
table.

We have to track our day in 15 minutes increments, some which are
billiable
or non-billable. I have set up the fomula that calculates the 15
minute
increments for each billable / non-billable. There are 4 billable and
4
non-billable categories, numbered 1 through 8 and these numbers are
placed
in
1 column which corrresponds with each time. What I can't figure out
is
how
to "pull" the data from the cells in each of the categories to one cell
representing each categorie. Each day will be different with different
times
for each category, so nothing remains static. Suggestions would be
greatly
appreciated.
