Sorry it took so long to get back to y'all. Dealing with the whirlwind of corporate life.
This was very helpful.
Thanks. :)

I have a table something like this:
A B
1234 1
1345 1
1345 2
1347 1
1355 1
1358 2
1366 1
1366 2
1375 1
Column A contains a variety of numbers which are usually unique, but
sometimes duplicate.
Column B contains either a 1 or a 2.
My need is to count the number of times Column B = 2 AND the
corresponding value for A is equal to the value for A of the previous
row.
So for example, in the table above the first time B=2 is in B3. I then
want the formula to slide over and compare to see if A3=A2 and if it
does, to include B3 in the count.
I've been playing around with all sorts of strange formulas using
COUNTIFS, OFFSET, MATCH, and others but I'm at a loss since I'm far from
an excel guru.
Please help.
Thanks.
