Thanks for your reply.
all the select elements are in a form.
But those selects can be referenced correcly after i insert some
unused element such as <input type="button" name="willberemove"/><br>
<font>Company:</font>
<font id="singlecompany" style="display: none;"></font>
<select name="companyID" id="companySelectID" WIDTH="130px" /><br>
<input type="button" name="willberemove"/><br>
<font>Division:</font>
<font id="singledivision" style="display: none;"></font>
<select name="divisionID" id="divisionSelectID"/><br>
<input type="button" name="willberemove"/><br>
it is ok now,but why not after i removed buttons?
