I want to highlight the lowest number in a range, only if that number does
not equal another number in the same range.

For instance, if in Cells A1:A6, the number 2 is the lowest number and all
other numbers are higher, I want the cell with the number 2 highlighted.

If in Cells A1:A6, the number 2 is the lowest number, but occurs twice, I do
not want any cells highlighted.

Any advice?
