I've been in SA-MP Wiki, i've added the codes for the joining server message, but nothing happens.
Here's what i did:

format(string, sizeof(string), "%s has joined the server.", playername );

Did i do anything wrong?
Please reply!

format(string, sizeof(string), "%s has joined the server.", playername );
SendClientMessage(playerid, Color , string);

That's On Player Connect

  GetPlayerName(playerid, name, 24);

  SendClientMessage(COLOR, string);
  return 1;
