Pagination Problems(PHP superglobal variable issue, undefined index)
<p>i am trying to implement pagination somewhere and i have this issue:</p>

<p>I have this part to change links:</p>

<pre><code>echo " &lt;a href='$_SERVER[SCRIPT_NAME]?Page=$Prev_Page'&gt;&lt;&lt; Back&lt;/a&gt; ";  
</code></pre>

<p>which gives this error for this part:</p>

<pre><code>$Page = $_GET["Page"];  
if(!$_GET["Page"])  
{  
</code></pre>

<p>It says undefined index..
Why do I get this Error?
Thanks</p>
