Newbie attempting to use Datepicker - it fails!

<html>
<head>
    <title>Datepicker Test 1</title>
        <script type="text/javascript" src="../jquery.js"></script>
        <script type="text/javascript" src="../jquery.ui.datepicker.min.js"></script>
<script language="JavaScript">
    $("document").ready(function() {
        alert("document ready");
            $("#SheetDropDead").datepicker();
        alert("SheetDropDead set");
        });
   
</script>
</head>
<body>
<form name="DPtest1" method="post" action="DatePickerTest2.asp">
            <input type="text" name="SheetDropDead" id="SheetDropDead">
</form>
</body>
</html>

I believe that the library containing datepicker is being loaded because I added an alert and that alert is seen.  Also seen are the two alerts at lines 8 and 10.  However, the datepicker does not show up.

Thanks
