    Sorry my english I dont speak verry well.
    use:

    =SUM(IF(LEN(A1:A100)>0,1/COUNTIF(A1:A100,A1:A100)))

    This is an Array Formula, you will have to use Ctrl+Shift+Enter NOT just enter. If done correctly the formula Excel will put {}'s round the formula.

    I can't lay claim to this, credit goes to David Hager for the 1/COUNTIF(A1:A100,A1:A100) bit and Aladin for the IF(LEN(A1:A100)>0 bit.
