That warnings says the indentation of your script is bad. You have to add an extra tab (or 4 spaces) in front of each line after you use an opening-bracket '{' and remove a tab (or 4 spaces) in front of each line after you used a closing-bracket '}'. This will make your script more readable. Without proper indentation your script will look like a mess. (Like Stuun's code here above).

Example:

pawn Код:

cmd:hello(playerid, params[])
{
    if(IsPlayerConnected(playerid))
    {
        if(IsPlayerInAnyVehicle(playerid))
        {
            SendClientMessage(playerid, -1, "Hello");
            RemovePlayerFromVehicle(playerid); 
        }
        else
        {
            SendClientMessage(playerid, -1, "Bye");
        }
    }
    return 1;
}
