@G4M3Ov3r - told from beggining,

pawn Code:

CMD:makeadmin(playerid, params[])
{
    new pID, value;
    if(!(PlayerInfo[playerid][pAdmin] >= 1338)) return SendClientMessage(playerid, 0xFF0000AA, " you are not authorized to use this command!");
    else if (sscanf(params, "ui", pID, value)) return SendClientMessage(playerid, 0xFF0000AA, "Usage: /makeadmin [playerid/partofname] [level 1-1338]");
    else if (value < 1 || value > 1338) return SendClientMessage(playerid, 0xFF0000AA, "Unknown level! Only 1 to 1338");
    else if(pID == INVALID_PLAYER_ID) return SCM(playerid, COLOR_GREY,"Invalid player id");
    else
    {
        new pName[MAX_PLAYER_NAME], tName[MAX_PLAYER_NAME], string[128];
        GetPlayerName(playerid, pName, MAX_PLAYER_NAME);
        GetPlayerName(pID, tName, MAX_PLAYER_NAME);
        format(string, sizeof(string), "You have promoted %s to Admin level %i", tName, value);
        SCM(playerid, COLOR_LIGHTBLUE, string);
        format(string, sizeof(string), "You have been promoted to Admin level %i by %s", value, pName);
        SCM(pID, COLOR_LIGHTBLUE, string);
        PlayerInfo[pID][pAdmin] = value;
    }
    return 1;
}

Or any another command that uses

PHP Code:

sscanf(params,"ui", example1, example2) 


does not work, getting Invalid Player ID/ Player Not Connected
