hy guys i am scriping on GUPS i want to a cmd !stunt1,2,3, so on so i do this
    else if ( strcmp( cmd, "!stunt", true ) == 0 )
   {
      SetPlayerPos(playerid,-987.98461,265.30059,8.81042);
      SetPlayerVehicle(playerid, 156 );
      format(szMsg, 128, "%s gone to do a stunt.",gPlayers[playerid]);
       SendClientMessageToAll( BLUE, szMsg );
      return 1;
   }
what i did wrong??it saying undefined symbol "SetPlayerVehicle" 
tell me the solution that when i type !stunt the player come to the saved position with car or bike
