Ok, now it works ...!!! I didn't understand I need to be on sheet1 before
running the macro :-)

....and just to finish...

now I've got values in columns A:D of sheet2...

in sheet 3 I've got data like in sheet1

is it possible to do the same operation and putting values coming from
sheet3 starting from the first free row of sheet2??

Example: after copy from sheet1, in sheet2 there are values in A1:D15...and
i wish to put data from sheet3 starting from A16...
