        var selectpackages = $("select[name='spackageindex']");
        var hipackages = $("input[name='hipackageindex']");
        var packagecount = $('#<%=txtCount.ClientID %>').attr("value");
        for (var i = 0; i < selectpackages.length; i++) {

            for (var m = 1; m <= packagecount; m++) {
                selectpackages[i].options.add(new Option(m, m));
            }
            selectpackages[i].value = hipackages[i].value;
