flash & xml fout (verplaatst niet)

[flapzucht]

ik heb de onderstaande code van internet.
het probleem is dat hij alle knoppen niet naast elkaar zet maar op dezelfde plek, waardoor je maar 1 knop ziet.
wie ziet de fout.

function menuOut(xml, movW, mcH, mcW, xpos, ypos)
{
xpos = xpos;
ypos = ypos;
startPos = xpos;
items = xml.firstChild.childNodes;
for (a = 0; a <= items.length - 1; a++)
{
subs = xml.firstChild.childNodes[a].childNodes;
iattrib = items[a].attributes;
item = _root.attachMovie("menuItem", "item" + a, a);
item.nametxt.text = iattrib.id;
subContain = _root.createEmptyMovieClip("subContain" + a, a + 1000);
for (b = 0; b <= subs.length - 1; b++)
{
attribs = subs[b].attributes;
sub = _root.subContain.attachMovie("menuItem", "sub" + b, b + 100);
sub.nametxt.text = attribs.id;
sub._y = mcH * b + mcH;
sub.itemUrl = attribs.theURL;
sub.onRelease = function ()
{
getURL(this.itemUrl, "_blank");
};
} // end of for
_root["subContain" + a]._visible = false;
_root["subContain" + a]._x = xpos;
_root["subContain" + a]._y = ypos;
item.num = a;
item.box.subsL = subs.length;
_root["item" + a].box.onRollOver = function ()
{
this._height = this.subsL * mcH + mcH + 8;
trace (this._height);
};
_root["item" + a].onMouseMove = function ()
{
mY = _root._ymouse;
mX = _root._xmouse;
this.subHit = _root["subContain" + this.num].hitTest(mX, mY);
this.itemHit = this.box.hitTest(mX, mY);
if (this.itemHit == true)
{
_root["subContain" + this.num]._visible = true;
}
else
{
_root["subContain" + this.num]._visible = false;
this.box._height = mcH;
} // end if
};
item._x = xpos - 10;
item._y = ypos;
xpos = xpos + xMove;
if (xpos >= movW - mcW / 2)
{
ypos = ypos + yMove;
xpos = startPos;
} // end if
} // end of for
} // End of the function
menu = new XML();
menu.ignoreWhite = true;
menu.load("http://purephotoshop.com/uploads/submen.xml");
menu.onLoad = function ()
{
menuOut(this, 350, 25, 125, 75, 15);
};

[dioneo]

Er staat in het script
xpos = xpos + xMove;maar die xMove zie ik nergens gedefinieerd.
