How come this variable echo's as 16?
<pre><code>$body = "Artist: " + $artist + "Size: " + $size + "Time: " + $time + "Concept: " + $concept + "Time: " + $time + "Mod: " + $mod + "Details: " + $details;
</code></pre>

<p>When I try to echo this variable, all that comes out is '16.' </p>

<p>Can you guys help?</p>
