Probably because you are running code against the XML recordsets, e.g.

Code:

CmbInit(cmbLastname, XMLLastnames.recordset, "last_name");

before they have finished downloading. Either place this code in a function called by window.onload or use the "ondatasetcomplete" event of the XML object to fire the individual CmbInit function, you'll need one for each data island.

Code:

<XML ID="XMLLastnames" src="XML/Lastname_list.xml" ondatasetcomplete="CmbInit(cmbLastname, this.recordset, 'last_name');"></XML>

The problem with this approach is you also need to be sure the listbox, "cmbLastname" has rendered as well so perhaps:

Code:

function loadListboxes()
{
    CmbInit(cmbLastname, XMLLastnames.recordset, "last_name");
    CmbInit(cmb_firstname, XMLFirstnames.recordset, "First_name");
    CmbInit(cmb_Place, XMLPlaces.recordset, "name");
    CmbInit(cmb_DocType, XMLDoctypes.recordset, "name");
    CmbInit(cmb_Keyword, XMLKeywords.recordset, "name");
}
<body onload="loadListboxes();">

would be better.
