Getting Notice: Undefined Index: id
<p>I'm making a forum software right now, just for some practice, and I'm getting this error when displaying the forums of the site.</p>

<p>This is my current start to it. It works, it just gives me this error:</p>

<p>Notice: Undefined index: id in C:\xampp\htdocs\forum\forums.php on line 15</p>

<pre><code>&lt;?php
include_once("connect.php");
mysql_select_db("forums");

$find = "SELECT ID,name,description FROM forums";  
$run_find = mysql_query("$find");
while($is = mysql_fetch_assoc ($run_find)) 
{
$id = $is['id'];
$name = $is['name'];
$des = $is['description'];

print "Forum : &lt;a href='topics.php?t=$id'&gt;". $name . "&lt;/a&gt;&lt;br/&gt;" .$des . "";
}

?&gt;
</code></pre>
