I am designing a sheet that shows a rota that will look like this

Name week 1 week 2 week 3
me 1 3 1
joe 1 2 4
dave 1 3 5

The numbers in the week colum will represent an area.
I would like a formula that will count how many numbers there are e.g how
many 1's in week 1 so i can see automatically that i have enough people in
that area. Eg if area 1 needs 3 people it will show up straight away if i
haven't got enough people roatad in that area. I can do condtionall
formatting on the end result but i cannot find somehting to give me the
result.


Cheers
