If I have a range, e.g. A1:A10, and in that range are various #'s, such as
1s, 2s, 3s or 4s. I'd like a formula in cell B1 that would produce all the
DIFFERNT #'s that are in that range. i.e.

If A1:A10 has only 1s in it, I'd like 1 in cell B1
If A1:A10 has 1s and 2s in it, I'd like 1,2 in cell B1
If A1:A10 has 1s,2s, and 3s in it, I'd like 1,2,3 in cell B1
If A1:A10 has 1s,2s, 3s, and 4s in it, I'd like 1,2,3,4 in cell B1
etc.
The number of times each # is in the range is irrelevent.

Thanks,

Steve
