Thanks Andy, I used a pivot table in this instance but I'll definetly save
that one for later!.

Hi Gerry - There is a nifty function called SUMPRODUCT which can be used
to
check any number of conditions and count the number of times all of them
are
met. It's not exactly intuitive, but once you get used to it you'll
probably
get a lot out of it. In your example, the list of people and tools they
used
is in SheetA, starting at A1. In SheetB set up a table with names down
the
left and tools across the top. If you started that table in A1 then the
first cell you need to populate is B2, correct? In B2 type (or paste):

=SUMPRODUCT(--(SheetA!$A$1:$A$6=$A2),--(SheetA!$B$1:$B$6=B$1))

Now copy that formula to all the other empty cells in the table. Of
course,
if your sheet names or cell locations are different, you'll to adjust the
formula.

You probably want to know how it works, so here is some explanation. Each
factor in SUMPRODUCT is a set of TRUE/FALSE evaluations. So the first
factor
tests to see if the names in column A of SheetA are equal to the name to
the
far left of the formula in SheetB. For example, the formula I provided
above
tests all the names to see which ones are equal to "John". The output
from
that par of the function is "True,False,False,True,False,False". The "--"
in
front of the factor converts True to "1" and "False" to "0". The second
factor does the same thing, but looks in column B of SheetA for the tools.
Its findings are also converted to 1's and 0's. SUMPRODUCT multiplies all
the pairs together (1X1,0X0,0X0,1X1,0X1,0X0) and then sums all those
products.

In case you're not familiar, the $ in front of row or column references
"anchor" those letters/numbers so that when you copy a formula to another
location they don't adjust. In the formula I provided above, you want
some
or the references to adjust and others not to. If you were to simply type
the adjusted formula in each cell in the table, you could omit the $.

Hope that helps. Write back if stuck.

Hi All

I'm trying to setup a formula which counts the amount of times 2
particular
conditions are true. From what I've read, =countif can only be used for
single conditions. I've tried some other options (see below) but all to
no
avail. Below is an eg of what I'm trying to do.

Basically, I have a worksheet (A) with several coulms and 20000 rows.

John word
Mary excel
Ann excel
John word
Mary word
Ann excel

I then have another worksheet (B) with just a list of user names

John
Mary
Ann

What I want to do is count the amount of times each user has used each
app.
So the final worksheet (B) would look like

word excel
John 2 0
Mary 1 1
Ann 0 2

As I say, my list of usernames is over 100 and the total rows is over
20000
so manual counting (even sorting my name) would be a chore. I also tried
the below formulae but it doesn't seem to work (found reference from the
web and adapted it to suit my needs but may have made a mistke?)

=SUM(IF($H2:$H4="John", IF($I2:$I4="word",1,0),0))

Apologies for the long post, if any one can point me in the right
direction
I'd really appreciate it.
regards
Gerry
