Connecting mySQL database

I'm having trouble setting up a connection to a phpMyAdmin database I have created. I am trying to create a sign up page. When a user enters their username and password I want the database to be updated. I'm getting the following error messages:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user: 'root@localhost' (Using password: NO) in W:\www\signup.php on line 2

Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in W:\www\signup.php on line 3

Warning: mysql_query() [function.mysql-query]: Access denied for user: 'ODBC@localhost' (Using password: NO) in W:\www\signup.php on line 10

Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in W:\www\signup.php on line 10 FailedAccess denied for user: 'ODBC@localhost' (Using password: NO)

Here is my code...

    $conn = mysql_connect("localhost","root","");
    $db   = mysql_select_db("loginpage", $conn);

    $user = $_POST['n'];
    $pass = $_POST['p'];
    $sql = "INSERT into phplogin VALUES(".$user.",'".$pass."')";
    $query = mysql_query($sql);

        echo "Failed".mysql_error();
        echo "Successful!";
