    //	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) {
