nop, that doesn't work,
i think it needs to be something like this

pawn Код:

public OnPlayerEnterVehicle(playerid, vehicleid, ispassenger)
{
    for(new i = 0; i < 27; i++) //Loop.  It counts to 11
    { //Open Bracket
        if(vehicleid == LSPDVehicles[i]) //If the vehicleid is an LSPD vehicle
        { //Open Bracket
            if(PlayerInfo[playerid][pFaction] != 1) //If the player is not in faction 1 (LSPD, in this case)
            { //Open Bracket
                ClearAnimations(playerid); //Clears their animation, preventing them from entering the vehicle.
                SendClientMessage(playerid, -1, "You don`t have the keys for this car."); //Sends a message to the player that he cannot enter it.
            {
        {
    for(new i = 0; i < 2; i++) //Loop.  It counts to 11
    { //Open Bracket
        if(vehicleid == MedVehicles[i]) //If the vehicleid is an LSPD vehicle
        { //Open Bracket
            else if(PlayerInfo[playerid][pFaction] != 2) // Faction 2
            { //Open Bracket
                ClearAnimations(playerid); //Clears their animation, preventing them from entering the vehicle.
                SendClientMessage(playerid, -1, "You don`t have the keys for this car."); //Sends a message to the player that he cannot enter it.
            } //Closed Bracket
        } //Closed Bracket
    } //Closed Bracket
    return 1; //Return a value
}
