Thank you very much to both of you. I tried and kept both corrections
and both work perfect, I think it sorts according first digit, like 25
is in front of 3, it returns 1,2,25,3,35,42,5 etc...however it is still
OK after having the unique values.

Really great help and of course and excellent UDF (still have to work
on it to understand...).

Regards,

Merry X-Mas and Happy Many Years...
