So my command blocks are like....broken. mainly one part of it: the tp command, the command that i want is: "/tp @p -543 168 -11". but when ever i put in the command into the command block it says "player not found". but i dont want it to affect the just one person, i want it to affect person using the command block! it does not even work when there more than 1 person one the server. i really want help on this
