If you use sscanf, this is how it should be.

CMD:setlevel(playerid,params[])
{
    new userid, level;
    
    if(sscanf(params, "ui", userid, level))
        return SendClientMessage(playerid, -1, "/setlevel [playerid/partofname] [level]");
        
    if(!IsPlayerConnected(userid))
        return SendClientMessage(playerid, -1, "The user is offline.");
        
    SetPlayerScore(userid, GetPlayerScore(userid)+level);
    SendClientMessage(playerid, COLOR_RED, "The level has been set.");
    return 1;
}
