Copy values between sheets

Hey

How can i copy values from sheet1 to sheet2 without empty cells gives the value 0?
Whenever i copy a range from sheet1 to sheet2 where there are some blank cells, the cells in sheet2 returns the value 0, where iI just want them to be blank like in sheet1. I know i can do it by typing "space" in the cells in sheet1 but that get overwritten when I copy something into the range.

Kind regards
