pawn Code:

CMD:setadminlevel(playerid, params[])
{
  new oID, oLvl;

  if (sscanf(params, "ui", oID, oLvl)) { return SendClientMessage(playerid, COLOR_WHITE, "... How to use it."); }

  if (PlayerInfo[playerid][pAdmin] > 0)
  {
    if (oID != INVALID_PLAYER_ID) 
    { 
       if (PlayerInfo[playerid][pAdmin] > oLvl) { PlayerInfo[oID][pAdmin] = oLvl; }
       else { return SendClientMessage(playerid, COLOR_WHITE, "... Can't set player as high or higher than you."); 
    }
    else { return SendClientMessage(playerid, COLOR_WHITE, "... ID not connected/valid."); }
  }
  else { return SendClientMessage(playerid, COLOR_WHITE, "... Not an admin."); }

  // Here you can spit out all the, admin has done blah blah, you have successfully blah blah.
  // You can do it here, because if not successful, any 1 of the else cases will exit early.

  return 1;
}

That should just about suffice.

It can be different, but I just wrote this off the top of my head in the reply, it makes sure the admin setting a user as an admin, can not make them of equal or higher admin level. The messages are just place holders, can change them and of course add all your format/broadcast etc where the comments are.

If this still gives you an invalid ID, it's an invalid ID, press TAB in game to find out what ID's are actually connected.
