local variable "string" shadows a variable at a preceding level
This means that you created a new variable somewhere which already exists somewhere else. In this case you've already created a variable called "string" in another function. Rename one of the two.

loose indentation
Wouldn't know how to explain this. I'm guessing it's the following code:

pawn Код:

if(Player[i][LockedCar3] == 1 && Player[i][Car3LinkID] == vehicleid)
{
            SendClientMessage(playerid, WHITE, "This vehicle is locked.");
    RemovePlayerFromVehicle(i);
}

change that to:

pawn Код:

if(Player[i][LockedCar3] == 1 && Player[i][Car3LinkID] == vehicleid)
{
    SendClientMessage(playerid, WHITE, "This vehicle is locked.");
    RemovePlayerFromVehicle(i);
}
