Datepicker CSS problem

I"m using datepicker within Wordpress. The js works correctly and the
value is put in the form field, however I've selected the Redmond
theme (which is blue) and instead I get green for the pop up.
Here is the code I am using:

<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/
jqueryui/1.7.2/themes/redmond/jquery-ui.css" type="text/css" />
<script type="text/javascript" src="http://beta.citycentric.com/wp-
content/jquery-ui/js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="http://beta.citycentric.com/wp-
content/jquery-ui/js/jquery-ui-1.7.2.custom.min.js"></script>
<script type="text/javascript">
    $(function() {
        $("#datepicker").datepicker({minDate: 0, numberOfMonths: 1});
    });
    </script>
If I place a reference within the html body of the page just above the
form field then I get a blue header bar in the pop up but still a
green background, so obviously there is a change from it loading the
new css file, but it still isn't right.
Here is that code:
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/
jqueryui/1.7.2/themes/redmond/jquery-ui.css" type="text/css" />
<div>Start Date:<input id="datepicker" type="text"
name="scheduledStartDate" /></div>
</div>
I'm stumped, any suggestions?
