Текст на шашечке таксиста

[SaNek2x2]

Доброе время суток
Вот создаю машины и аттачку к ним объект. На объекте пишу текст.

taxicar[0] = AddStaticVehicleEx(426,850.6849976,-1550.4680176,13.2900000,0.0000000,6,6,420000); //Premier 
    taxicar[1] = AddStaticVehicleEx(426,847.1699829,-1550.4489746,13.2889996,0.0000000,6,6,420000); //Premier 
    taxicar[2] = AddStaticVehicleEx(426,843.2570190,-1550.4940186,13.2880001,0.0000000,6,6,420000); //Premier 
    taxicar[3] = AddStaticVehicleEx(426,839.0349731,-1550.5050049,13.2880001,0.0000000,6,6,420000); //Premier 
    taxicar[4] = AddStaticVehicleEx(426,834.7990112,-1550.5539551,13.3179998,0.0000000,6,6,420000); //Premier 
    taxicar[5] = AddStaticVehicleEx(426,830.7189941,-1550.4749756,13.3240004,0.0000000,6,6,420000); //Premier 
    taxicar[6] = AddStaticVehicleEx(426,826.5349731,-1550.5369873,13.3230000,0.0000000,6,6,420000); //Premier 
    taxicar[7] = AddStaticVehicleEx(426,822.0529785,-1550.5579834,13.3479996,0.0000000,6,6,420000); //Premier 
    taxicar[8] = AddStaticVehicleEx(426,817.6079712,-1550.5899658,13.3710003,0.0000000,6,6,420000); //Premier 
    taxicar[9] = AddStaticVehicleEx(426,813.4080200,-1550.5649414,13.3699999,0.0000000,6,6,420000); //Premier 
    taxicar[10] = AddStaticVehicleEx(426,809.0729980,-1550.5610352,13.3699999,0.0000000,6,6,420000); //Premier 
    taxicar[11] = AddStaticVehicleEx(426,800.4320068,-1550.4399414,13.4499998,0.0000000,6,6,420000); //Premier 
    taxicar[12] = AddStaticVehicleEx(426,804.9140625,-1550.5000000,13.4139996,0.0000000,6,6,420000); //Premier 
     
    for(new tx = 0; tx < 13; tx++) 
    { 
        taxiobj[tx] = CreateDynamicObject(19308, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0); 
        AttachDynamicObjectToVehicle(taxiobj[tx], taxicar[tx], 0.000000, -0.499999, 0.924999, 0.000000, 0.000000, 0.000000); 
        SetDynamicObjectMaterialText(taxiobj[tx], 0, "Свободна", 50 , "Arial", 30, 0, 0xFF000000, 0xFFFF8200, 1); 
    }

Затем его меняю:

new tarif; 
                if(sscanf(inputtext, "d",tarif)) return SPD(playerid, 28, DIALOG_STYLE_INPUT, "{4169E1}Такси | {FFFFFF}Тариф", "{FFFFFF}Выберите тариф вашего такси\nНе больше 300$", "Ввод", "Отмена"); 
                GivePlayerCash(playerid, -RENT_TAXI_CAR); 
                SendClientMessage(playerid, COLOR_WHITE, "Вы начали свой рабочий день. Ищите клиентов."); 
                for(new tx = 0; 13 < tx; tx++) 
                { 
                    if(GetPlayerVehicleID(playerid) == taxicar[tx]) 
                    { 
                        new string[128]; 
                        format(string, sizeof(string), "%d$", tarif); 
                        SetDynamicObjectMaterialText(taxiobj[tx], 0, string, 50 , "Arial", 30, 0, 0xFF000000, 0xFFFF8200, 1); 
                    } 
                }

В итоге текст не меняется
