    Count Duplicates in a List (2000)

    I need to count the entries in a long cell range, but I don't want to count duplicates. Can anyone help with a formula to do this?

    Thanks, I tried the formula below but it returned a #VALUE for the result. The entries in the cells are a combination of letters and number i.e. HI458a

    =SUM(IF(FREQUENCY(IF(LEN('H off'!J70:J92)>0,MATCH('H off'!J70:J92,'H off'!J70:J92,0),""),IF(LEN('H off'!J70:J92)>0,MATCH('H off'!J70:J92,'H off'!J70:J92,0),""))>0,1))

    Hi stanlafayette,

    I think your mentioned formula is a array formula, must enter with Shift+Ctrl+Enter

    Or you can try the below count unique formula :

    =SUMPRODUCT(('H off'!J70:J92<>"")/COUNTIF('H off'!J70:J92,'H off'!J70:J92&""))

    Regards
