    Making a list of unique items in a column

    Arrgh-
    I've been using the following snippet to create a list of unique values in a column. It works great as long as the list of unique values and the column being parsed are on the same table. I'm having the darndeest time doing this where the list is on one table in a workbook and the column of mixed values in another table in the same workbook. Here's the formula where both columns are on the same page:

    {=IF(ISNA(OFFSET($A$1,MATCH(0,MMULT(--TRANSPOSE(TRANSPOSE($A$1:$A$13)=B$1:B1),ROW(INDIRECT("1:"&ROW()-1))/ROW(INDIRECT("1:"&ROW()-1))),0)-1,0,1,1)),"",OFFSET($A$1,MATCH(0,MMULT(--TRANSPOSE(TRANSPOSE($A$1:$A$13)=B$1:B1),ROW(INDIRECT("1:"&ROW()-1))/ROW(INDIRECT("1:"&ROW()-1))),0)-1,0,1,1))}

    The above goes in the second cell down (B2) where B1 would be the first value in the mixed column, (eg B1=A1)
    ...and here's the one I've been putzing with between pages:

    =IF(ISNA(OFFSET(data!D2:D100,MATCH(0,MMULT(--TRANSPOSE(TRANSPOSE(data!D2:D100)=A$3:A3),ROW(INDIRECT("1:"&ROW()-1))/ROW(INDIRECT("1:"&ROW()-1))),0)-1,0,1,1)),"",OFFSET(data!D2:D100,MATCH(0,MMULT(--TRANSPOSE(TRANSPOSE(data!D2:D100)=A$3:A3),ROW(INDIRECT("1:"&ROW()-1))/ROW(INDIRECT("1:"&ROW()-1))),0)-1,0,1,1))

    ...where "data" is the name of the table with the mixed column.

    Try placing the table in the same sheet first, and applying the formula so that it works as you described... then cut and paste that table to the data sheet. The formula should automatically adjust the ranges to include the sheetname.
    Where there is a will there are many ways.

    Why not Advanced Filter unique entries?
    Hope that helps.

    Ooooh, that worked w/my example. This I can use to reverse engineer a solution. THANKS!

    Re: Making a list of unique items in a column

    I'm having a problem making a list of unique items in a column.

    The column is on one page of a workbook (D2:D14) and the list is on another page. It works fine when the list is from A1:A13, however when I cut and paste down 2 cells to A3:A15. The function has problems.

    Here is the function:

    {=OFFSET(data!$D$2,MATCH(0,MMULT(--TRANSPOSE(TRANSPOSE(data!$D$2:$D$14)=A$1:A1),ROW(INDIRECT("1:"&ROW()-1))/ROW(INDIRECT("1:"&ROW()-1))),0)-1,0,1,1)}

    I've spent some time tinkering w/it and can't seem to make progress...is anyone familiar w/the above issue?

    I've attached a copy of the workbook for review. Thanks.
