You've a mistake here:

if(GetVehicleModel(GetPlayerVehicleID(playerid) ==543))

You've missed closing ) on GetVehicleModel Function.
Correct Code:

pawn Код:

if(GetVehicleModel( GetPlayerVehicleID(playerid) ) ==543)
    {
    trucker[playerid] = 1;
    SetPlayerCheckpoint(playerid,-60.9470,-1132.2079,1.0781,243.6163,7.0);
    SendClientMessage(playerid, 0xFFFFFFFF, "SERVER: You're now on {FF8000FF}trucking mission.");
    }
    else
    {
    SendClientMessage(playerid, 0xFF0000FF, "SERVER: You must be inside a Sadler to perform this command.");
    return 1;
