Look at: /hotdogs command , it will appear an aditional message that say that the player is not in a car even if he is

pawn Code:

if (strcmp("/hotdogs", cmdtext, true) == 0)
    {
        if(GetVehicleModel(GetPlayerVehicleID(playerid)) == 588)
        {
            HotDog[playerid] = 1;
            new name[MAX_PLAYER_NAME], string[256];
            GetPlayerName(playerid, name, sizeof(name));

            format(string, sizeof(string), "{0000FF}[RgX:INFO]{FF0000}%s {FFFFFF}is now a Hotdog Delivery.", name );
            SendClientMessageToAll(-1, string);

            SetPlayerCheckpoint(playerid, 804.1773,-1455.8715,13.1253,10);
            SendClientMessage(playerid, -1,"{00FFFF}Job{FFFFFF}: Follow the red markers");
            return 1;
        }
         SendClientMessage(playerid, -1,"{CE0000}You have to be on a Hotdogs car to start the job!");
    }
    return 0;
}

Anyway good job..

You should put an else:

pawn Code:

else SendClientMessage(playerid, -1,"{CE0000}You have to be in a Hotdogs car to start the job!");
