jQuery(" ").datepicker({ }) is not working in IE7/8

[Ravichandra Ravi]

My code is

jQuery(function() {
jQuery("#fromDatepicker").datepicker({
changeMonth : true,
changeYear : true,
dateFormat: 'mm/dd/yy'
});

jQuery("#toDatepicker").datepicker({
changeMonth : true,
changeYear : true,
dateFormat: 'mm/dd/yy'
});
});
and input fields are

<input type="text" id="fromDatepicker" name="searchStartDate" size="20">
<input type="text" id="fromDatepicker" name="searchStartDate" size="20">


i am using

jquery-1.6.2.js
jquery-1.6.2.min.js
jquery.ui.core.js
jquery.ui.datepicker.js
jquery.ui.datepicker.css

the calender is displaying but,

when I select a date on the calendar, the date is not selecting and not entering into the text field(searchStartDate and searchStartDate ).
Please Help me how to resolve this problem.
