[Misiur]

This is quite complex. Could describe a little more what is wrong? I mean, you can fully complete one delivery, and after you return to base to get money, you can't take any new deliveries and get error about mismatching trucks? You are calling

pawn Код:

PlayerInfo[playerid][pDeliveryVeh] = -1;

so it shouldn't happen

You can actually shorten your

pawn Код:

if(DeliveryMission[playerid] == 1) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[1],1);
        else if(DeliveryMission[playerid] == 2) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[2],1);
        else if(DeliveryMission[playerid] == 3) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[3],1);
        else if(DeliveryMission[playerid] == 4) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[4],1);
        else if(DeliveryMission[playerid] == 5) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[5],1);
        else if(DeliveryMission[playerid] == 6) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[6],1);
        else if(DeliveryMission[playerid] == 7) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[7],1);
        else if(DeliveryMission[playerid] == 8) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[8],1);
        else if(DeliveryMission[playerid] == 9) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[9],1);
        else if(DeliveryMission[playerid] == 10) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[10],1);
        else if(DeliveryMission[playerid] == 11) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[11],1);

to

pawn Код:

if(DeliveryMission[playerid] >= 1 && DeliveryMission[playerid] <= 11) return TogglePlayerDynamicCP(playerid, DeliveryJobCP[DeliveryMission[playerid]], 1);
