i have this user control works fine, the only problem is when user is using user control 1 and type in address and not select address so javascript validation appears but it appears in both user control it should appear only to that user contorl which user is using currently

pls advice

when i add another instance of same user control like this

<%@  control language="C#" autoeventwireup="true" codebehind="GoogleAddressDifference.ascx.cs"
    inherits="EcheckCallV2.usercontrol.GoogleAddressDifference" %>
<script type="text/javascript">
    var fromAddress;
    var toAddress;
    $(function () {
        var textbox1 = $(this).find('[id*=txtfrom]');
        var textbox2 = $(this).find('[id*=txtto]');
        ApplyAutoComplete(textbox1);
        ApplyAutoComplete(textbox2);
        $(textbox1).blur(function () {
            var address = $(this).val();

            if (address == fromAddress) {
                $('[id*=lblFrom]').hide();
            } else {
                $('[id*=lblFrom]').show();
            }
        });
        $(textbox2).blur(function () {
            var address = $(this).val();

            if (address == toAddress) {
                $('[id*=lblTo]').hide();
            } else {
                $('[id*=lblTo]').show();


            }
        });
    });
    function ApplyAutoComplete(input) {
        google.maps.event.addDomListener(window, 'load', function () {
            var places;
            for (var i = 0; i < input.length; i++) {
                var options = { types: ['(regions)'] };
                places = new google.maps.places.Autocomplete(input[i], options);
            }
            google.maps.event.addListener(places, 'place_changed', function () {
                if ($(input)[0].id == $('#<%=txtfrom.ClientID%>')[0].id) {
                    fromAddress = places.getPlace().formatted_address;
                    $('[id*=txtfrom]').val(fromAddress);
                    $('[id*=txtfrom]').trigger("blur");
                } else if ($(input)[0].id == $('#<%=txtto.ClientID%>')[0].id) {
                    toAddress = places.getPlace().formatted_address;
                    $('[id*=txtto]').val(toAddress);
                    $('[id*=txtto]').trigger("blur");
                }
            });
        });
    };
