First of all change your VehiclePrices declaration to this :

Quote:

new VehiclePrices[47][2]

Then use this code:

PHP Code:

stock ShowVehicleDialog(playerid)
{
    new model = GetVehicleModel(GetPlayerVehicleID(playerid)), found = -1;
    for ( new i = 0; i < sizeof(VehiclePrices); i++ )
    {
        if(model == VehiclePrices[i][0])
        {
            found = i;
            break;
        }
    }    
    new str[100];
    if(found == -1)str = "Model not found";
    //note the difference in format parameters in next line
    else format(str, sizeof(str), "%s %d "COL_DGREEN"$%d", VehicleNames[model-400], model, FormatNumber(VehiclePrices[found][1]));
    Dialog_Show(playerid, BUYVEHICLE, DIALOG_STYLE_LIST, str,"Test", "Seз", "İptal");    
    return 1;
}
