Response.Write("var user;")
Response.Write("var pass;")
Response.Write("var con;")
Response.Write("var mail;")


        Response.Write("function checkUser(){")
        Response.Write("var UserName=document.getElementById('Username').value;")
        Response.Write("var Num=document.getElementById('num').value;")
        Response.Write("var i=0;")
        Response.Write("var result=0;")
        Response.Write("while(i<Num){")
        Response.Write("if(UserName==document.getElementById('User'+i).value){")
        Response.Write("result=1;")
        Response.Write("}")
        Response.Write("i++;")
        Response.Write("}")
