    What was your error message?
    You can't expect someone to run your code...

    They aren't fatal errors. They are PHP warnings. It's just letting you know that $_GET['id] is undefined because the "id" param was NOT assigned a value.

    Use this to avoid warnings:

    
$id = isset($_GET['id']) ? $_GET['id'] : "";
$marks = isset($_GET['marks']) ? $_GET['marks'] : "";
$selection = isset($_GET['selection']) ? $_GET['selection'] : "";
$correct = isset($_GET['is_correct']) ? $_GET['is_correct'] : "";
