Excel summing up values of scattered data

Hello,

I am looking for how to make a cell in excel that tells me how many of a certain item I have. In column b I have values (numerical) of certain items corresponding to column c next to it ie...
B C
1 x
2 y
3 z
5 x
8 y

what I want is a cell that I can have list output like this:

input output (this is where I need help)
x 6
y 10
z 3

tried using search() but that returns an array and tried using row() but first I would need to know the cell location of a found string

THANKS A TON IN ADVANCE
