"List" is a defined name range (no quotes)

=IF(ISERR(SMALL(IF(COUNTIF(List,List)=1,ROW(INDIRE CT("1:"&ROWS(List)))),ROWS($1:1))),"",INDEX(List,S MALL(IF(COUNTIF(List,List)=1,ROW(INDIRECT("1:"&ROW S(List)))),ROWS($1:1))))

ctrl+shift+enter, not just enter
copy down as far as needed

Not sure how to do this, I'm on office 2007 and I dont see a way to do this
with Remove Duplicates as it still leaves me with one of each number.
