<script type = "text/javascript" >
        function WriteName(id) {
            var temp = document.getElementById('<% = Label7.ClientID %>').style.visibility = "hidden";
        }
        function falselab(id) {
            var temp = document.getElementById('<% = Label4.ClientID %>').style.visibility = "hidden";
            
        }
