You'd have to create a new source without the dupes. There's no way to
remove dupes from the validation list itself.

Hi. I want to use a range of cells, all in part of a column, as a
validation list source. Here's the command I have in the cells to
which I want to apply the validation list source:

=(OFFSET(RangeStart,1,0)):(OFFSET(RangeEnd,-1,0))

The problem I'm having is that if duplicate values exist between
RangeStart and RangeEnd, I get duplicate values in my validation list.
How could I eliminate duplication from the displayed pulldown
validation list?

Thanks for any input!
