Dynamisk dropdown

Hej
Jeg sidder og pusler med en dobbelt dropdown. dvs den skal først vise den ene og derefter vise/lave den anden select.

Herefter skal den gå til den side man vælger:

men jeg kan ikke få det til at virke.

der vises kun TRE ( ? ) tomme dropdowns HJÆLP


<SELECT NAME="Menu1" onChange="changeListOfPages(this.form)">
<SCRIPT LANGUAGE="JavaScript">
with (document) {
tot = Menu1Options.length;
        for (i = 0; i < tot; i++)
        writeln("<OPTION>" +Menu1Options[i]);
}

</script>
</SELECT>


<SELECT NAME="Menu2" onChange="gotoPage(this.form)">

<script>
with (document) {
//writeln('<OPTION>""</option>');
        for (i = 0; i < maxLength; i++)
        writeln("<OPTION>" +Menu2Options[i]);
        writeln("</SELECT>");
    for (i = maxLength; i > Menu2OriginalLength; i--)
        { DoubleDropDownMenu.Menu2.options[i] = null; }
changeListOfPages();
}
