php data checking and clarification
<pre><code>if( isset( $_POST['aquafina'] ) &amp;&amp; $_POST['aquafina'] != '' ) 
{
    $message .= "AquafinA: ".( $_POST['aquafina'] ). "\n";
}
</code></pre>

<p>Noob, questions and clarifications:</p>

<p>This means != (not equal to empty), right?</p>

<p>And </p>

<pre><code>if( isset( $_POST['numSelections'] ) &amp;&amp; $_POST['numSelections'] &gt; 0 &amp;&amp;

$_POST['numSelections'] &lt; 40 )
</code></pre>

<p>This means less than 40 for numSelections, right?</p>

<p>Just need some clarification, thank you for not flaming.  </p>
