HI - New to JQuery, need a little help

I am actually quite new to all this web development, but getting there.
 
JQuery is something new i have been looking at, looks good so far, but i have an issue with the datepicker
i need to retrive the value placed in the text box so that i can save it to a Mysql database
 
I am using dreamweaver and have added Jquery datepicker as an extension
 
so i add it to a form, and it works fine, i can pick a date that gets added to the text box, the following code has been added
 
 <input type="text" size="30" value="Click to show datepicker" id="jQueryUICalendar1"/>
        </p>
        <p></p>
        <script type="text/javascript">
// BeginWebWidget jQuery_UI_Calendar: jQueryUICalendar1
jQuery("#jQueryUICalendar1").datepicker();




// EndWebWidget jQuery_UI_Calendar: jQueryUICalendar1
        </script>
 
 
i would normally post the value of textbox jQueryUICalendar1 when writing out to the database
 
GetSQLValueString($_POST['jQueryUICalendar1'], "text"),
 
but the value is NULL
 
how do i retrive the correct date value?
i know a bit more about PHP than i do java
 
Thanks for you help in advance, looking forward to using more Jquery
