js-menu und layer

[frank]

hallo liebe leute.

hab eine frage:
ich habe im inet ein schönes java-script-menu gefunden.
da ich leider kein js kann, sondern nur in der lage bin, es nach meinen wünsche anzupassen, stehe ich jetzt vor folgendem problem:

das js-menu wird absolut positioniert, hab unten den quellcode drangehängt. da gibts ne variable namens var m_margin = 0;.
nun hab ich allerdings ein layer, welches center ist. d.h. das doofe menu kann sich net anpassen.

//hier das menu

var m_align    = 'left';
var m_margin   = 0;
var m_top      = 90;
var m_popup    = 'auto';
var m_showlink = 'style'
var m_icn    = new Array(new Image(), new Image(), new Image(), new Image());
m_icn[0].src = "link_right.gif";
m_icn[1].src = "link_right.gif";
m_icn[2].src = "link_right.gif";
m_icn[3].src = "link_right.gif";

var m_df    = new Array();
m_df[0]     = new Array();
m_df[0][0]  = new M_menu (false, "center", 0);
m_df[0][1]  = new M_entry("Home", "index.html"     , "_self", "nav", 110, 18, 0, "#000066", "#9FAFD3",  1, "");

m_df[1]     = new Array();
m_df[1][0]  = new M_menu (true, "left", 1);
