Error retrieving information from user cookie
<p>When I run the project, I get this line highlighted with an error:</p>

<pre><code>string cartID = context.Request.Cookies["Cinemax_CartID"].Value;
</code></pre>

<p>The message is as follows:</p>

<pre><code>Object reference not set to an instance of an object.
</code></pre>

<p>Thanks for any suggestions! </p>
