<?php
    mysql_connect("localhost","root","") or die("not connected");
    mysql_select_db("try") or die("no db found");

    if(isset($_POST['submit'])){
        $username = $_POST('username');
        $Password = $_POST('Password');
        $query="insert into login(username,Password) values('$username','$Password')";
    if(mysql_query($query)){
            echo "Data is inserted successfully!";
        }


    }
    ?>

I have encounter few problems and now is the best one as it produce blank page when I click submit button, can you tell me where I could possibly go wrong?

$query="insert into login(username,Password) values('$username','$Password');"

$query="insert into login(username,Password) values('$username','$Password')";
