variable not displaying in output?
<p>I perform the following..</p>

<pre><code>$output = $_GET['_url'];
echo $output;
//displays the url in $output, correctly

if ( isset($_POST['email'])){
//'email' is not empty

echo "url: " . $output;
//it displays "url: " but does not display the url from $output
}
</code></pre>

<p>I enter an email and on submit it does not echo the $output var during the if post.. only outside of it.</p>

<p>Why is this the case and what can I do to fix it?</p>
