Your checkbox input element with name "Rememberme" is missing a value attribute. I included in the code below.

<p>
<input type="checkbox" name="RememberMe" value="YouForgotMe"/> Remember me <br />
</p>


Also don't forget to enclose your code in code tags!

Cheers.

Another thing you should know

A checkbox only carries a value if it's checked, however when it's not, the PHP won't register the variable passed.

instead of using

$remember = $_POST['checkbox_variable'];


Try using

$remember = (isset($_POST['checkbox_variable']) ? true : false);


That way, you're not camouflaging any errors, and getting nice yes or no answer.

Hope this helped

A value attribute is not required. Browsers will simply send through the string On when there's no value set.

The reason it's undefined is because if the checkbox is not ticked, it doesn't get sent through - Exactly like huzi8t9 said, this is the key to fixing it.
