I am trying to insert my form's data radio buttons into my mysql database. it works very well but when i skip any one value of my radio button,as this is more than 20, its giving error that

Notice: Undefined index: qr1 in C:\wamp\www\exam\contents\omr.php on line 134
Call Stack
#   Time    Memory  Function    Location
1   0.0018  148808  {main}( )   ..\omr.php:0

but in the database, i am getting my desired result, means all the values are got inserted and which radio button is not put in the form, inseting with blank, as i want.. and also executing lines which is written after mysql query in the program.
so how can i debug my error??

        $username = $_COOKIE['ID_my_site']; 
        $pass = $_COOKIE['Key_my_site']; 
        $check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error()); 
        while($info = mysql_fetch_array( $check ))   
             //if the cookie has the wrong password, they are taken to the login page 
            if ($pass != $info['password']) 
                header("Location: login.php");
