My formulas:
in cell B1 = SMALL($A$1:$A:$10,1)
in cell B2 and down =TRUNC(SMALL(IF($A$1:$A$10B1,$A$1:$A
$10+0.001*ROW($A$1:$A$10)),1))

This is what i'm getting...

Data set:
A B
1) 10 10
2) 20 20
3) 30 30
4) 40 40
5) 50 50
6) 30 0
7) 20 20
8) 50 50
9) 60 60
10) 100 100

Looking at my formula you'll see that the results of B6 make no
sense. Can anyone explain this or help me fix this? I should be
getting: 10, 20, 30, 40, 50, 60, and finally 100 with 0's in the last
3 cells.

Other info, what i'm trying to do with this formula is extract unique
numbers (non-repeating) from a large data set. Some of the data in
column A will be repeating, but I only am interested in a condensed
list.

Thanks,
Daniel
