That's exactly what you understand. You suggest me do it with Auto Filter.
It's a good idea. Me, personally, I know how to make with Auto Filter so to
extract exactly what I want from a range of data, by adding a line with column
names above the data range and then apply the auto filter. Yes. It's not a
problem, but user, he/she may find it difficult, so I thought to ease it by the
user form. To offer the user  the possibility to enter the criteria  in the
fields, then get whatever he/she is looking for by simple click of the button.
You see. If you have any suggestion of how to make this out, please help.
