Hello.I'm Very new to this forum and to Pawn.i Was trying to Get the Player's vehicles(the vehicles which a player owns) and then spawn them.but i get lots of error like Array must be index and other that i have attached in the end of the post.i really have no idea why i get these errors and i tried searching ****** and the forum,but i couldnt get a result

pawn Code:

GetPlayerVehicles(playerid){
    new vehicles[50][32];
    new ind;
    ind=0;
    for(new i;i<MAX_VEHICLES;i++)
    {
        if(VehicleInfo[i][cOwner]== PlayerInfo[playerid][pName])
        {
            vehicles[ind]=i;
            ind++;
        }
    }
    return vehicles;
}
SpawnPlayerVehicles(playerid)
{
    new fields = GetPlayerVehicles(playerid);
    new length[10] = sizeof(fields);
    new id;
    for (new i;i<length;i++)
    {
        id = strval(fields[i]);
        CreateVehicle(VehicleInfo[id][cModel],VehicleInfo[id][cLocationX],VehicleInfo[id][cLocationY],VehicleInfo[id][cLocationZ],VehicleInfo[id][cAngle],VehicleInfo[id][cColor1],VehicleInfo[id][cColor2],0);
        }
}

Errors:

array must be indexed (variable "-unknown-")// on new fields = GetPlayerVehicles(playerid);
array must be indexed (variable "length")
invalid subscript (not an array or too many subscripts): "fields"//On id = strval(fields[i]);
