Hi, I initially had that problem concerning editing last names. After playing around with my controller for about fifteen minutes, I figured out you only have to press select to go from first to last name. Pressing space will not do it, just press select and you will see a faint flashing dash on the last name zone or nothing at all, but go ahead and edit. When you edit a last name, the player's new last name shows up on the back of his shirt. I am creating River Plate now, I made the front and back of their uniform since the stripe is in both the front and back of their uniforms. The name and player number is written in white so in order to better them from a distance I put a black box on the back of the shirt to make the white lettering more visible. This game is so cool, in terms of uniform editing.
