Try this. Changed two things. You were using the variable name as a string, when it was an integer. I then changed the fact the namestring, of which was the location of it, had MAX_PLAYER_NAME, which is only 24 characters. So if someone were to have about 10 characters, it would cut off part of his name because it passed the limit.

Hope I helped.
