I am using a simple JavaScript to receive a row from [Data Extension Server-Side JavaScript Functions] [1] in ExactTarget and display the retrieved row on  Landing Page . As below

    Platform.Load("core", "1");
    var birthdayDE = DataExtension.Init("birthdayDE");
    var filter = {
        Property: "EmailAddress",
        SimpleOperator: "equals",
        Value: "[email protected]"
    };
    var data = birthdayDE.Rows.Retrieve(filter);
    if (data.length > 0) {
        Write("table border='1' cellpadding='2' cellspacing='3' style='border-collapse:collapse;");
        for (var i = 0; i <= data.length; i++) {
            var d = data[i];
            Write("tr");
            for (var key in d) {
                Write("td" + d[key] + "/td");
            }
            Write("/tr");
        }
        Write("/table");

Somehow it does not show me any results nor give any errors.
