Some where in your code put

PHP код:

forward playerOnLeaveCheckPoint(playerid);
public playerOnLeaveCheckPoint(
     DisablePlayerCheckpoint(playerid);
     return 1;
} 


Then in your main gamemode where it says

PHP код:

public OnPlayerLeaveCheckpoint(playerid) {
     playerOnLeaveCheckPoint(playerid); // <-- Put that 
}
