    <script type="text/javascript">
        var cult = "";
//        $(window).load(function() {
            function pageLoad(sender, arg) {
                PageMethods.Session("Lang", OnCallComplete, OnCallError);
            }
            function OnCallComplete(result, userContext, methodName) {

                cult = result;
                var p = $("#b");
                var pos = p.position();
                var sub = document.getElementById("men");
                sub.top = pos.top + 70;
                alert(cult);
                if (cult == "en-US") {
                    sub.left = pos.left;


                }
                if (cult == "ar-LB") {

                    sub.left = pos.left - 70;
                }


                $("#men").offset({ left: sub.left, top: sub.top });
            }

            function OnCallError(error, userContext, methodName) {

                if (error !== null) {
                    alert(error.get_message());
                }
            }
