Assuming that your values in column B start at B1, try the following.

In C1 type 1

In c2 type =IF(ISERROR(MATCH(B3,$B$2:B2,0)),C2+1,C2) and then fill this formula down to the same row as the last value in column B

The number in this last row in column C is then the number of Unique values you have.
