Getting "No Data Found." with the Following Code... Help!!

I am simply getting a "No Data Found." message displayed within my ActiveWidget table. Below is the code that I'm using...

My main page code:

<script language="javascript">

<!--



    //	create ActiveWidgets data model - XML-based table

    var table = new Active.XML.Table;



    //	provide data URL

    table.setURL("xmldata.php");



    //	start asyncronous data retrieval

    table.request();



    //	define column labels

    var columns = ["ID", "Institution", "Country", "Status", "Exp. Date", "Research Collab.", "Faculty Exch.", "Student Exch.", "Grad. Exch.", "Undergrad. Exch."];



    //	create ActiveWidgets Grid javascript object

    var obj = new Active.Controls.Grid;



    obj.setAction("click", function(src){  

        var i = src.getProperty("item/index");  

        var j = src.getColumnProperty("index");  

        if (j==1) {  

            var link = "imoa_edit.php?imoaid=" + this.getDataProperty("text", i, 0); 

        	parent.hideSearchbox();

            document.location.href=link; 

        } ;  

    

    });  



    var row = new Active.Templates.Row;

    row.setEvent("onmouseover", "mouseover(this, 'active-row-highlight')");

    row.setEvent("onmouseout", "mouseout(this, 'active-row-highlight')");

    obj.setTemplate("row", row); 		



    //	provide column labels

    obj.setColumnProperty("texts", columns);



    //	provide external model as a grid data source

    obj.setDataModel(table);



    //	write grid html to the page

    document.write(obj);



//-->

</script>

The source XML "xmldata.php" page:

</imoa>

Any ideas why the widget is not working with this code, and simply saying "No Data Found."??

Thanks for your help!!
