Try to put this:

pawn Код:

if (IsPlayerInAnyVehicle(playerid)) 
{
  SendClientMessage(playerid,COLOR_GREEN,"You are already in a vehicle.");
  return 1;
}

Instead of this:

pawn Код:

if (IsPlayerInAnyVehicle(playerid)) return SendClientMessage(playerid,COLOR_GREEN,"You are already in a vehicle.");
