[jQuery] Can not get Select

[neil]

<select name="licenseeID" id="licenseeSelectID" /><br>
<table><tr><td>Select</td><td>FileName</td><td>Date</td></tr> </table>
<div id="tablediv"></div><br><br><br><br><br><br><br>
<font>Company:</font>
<font id="singlecompany" style="display: none;"></font>
<select name="companyID" id="companySelectID" WIDTH="130px" /><br>
<font>Division:</font>
<font id="singledivision" style="display: none;"></font>
<select name="divisionID" id="divisionSelectID"/><br>
i can reference the fist select 'licenseeID' and populate it.

but the third 'divisionID' can not be referenced,which says 0.options.

 var licenseeid=$('#licenseeSelectID').val();
 $('#divisionSelectID')[0].options.length=0;
