[PHP] Need little help with a small script

[Outbreaker]

HI,

I try to do a little script for Joomla (CMS) that would add a HTML "<div></div>" tag line based on the first category page (entry page) and the browser user-agent.

But the problem i have is to only run the script on the first category page (entry page).

This is the working PHP Script that would outputting a different "<div></div>" tag if a user-agent.is detected.

if (preg_match('/(Test1-Bot|Test2-bot)/i', $_SERVER['HTTP_USER_AGENT']))
{
  echo '<div class="cloud1">';
}
else
{
  echo '<div class="cloud2">'; 
}
<p>Some HTML Output</p>
</div>

So now the problem is that i want to run the above PHP Script only on the first category page (entry page) but i have problems to code this (Beginner).

This script would show it on all Blog pages:

if ( 
$option == 'com_content' 
and $view == 'category' 
and $id == '8' 
and $Itemid == '101' 
and $jinput->get('layout') == 'blog' /*!*/ 
) return XXX;

And this script would show it only on the Blog page 2.

if ( 
$option == 'com_content' 
and $view == 'category' 
and $id == '8' 
and $Itemid == '101' 
and $jinput->get('layout') == 'blog' /*!*/ 
and $jinput->get('limitstart') == '4' /*!*/ 
and $jinput->get('start') == '4' 
) return XXX;

How could i code a script that would run the above user-agent script only on Blog Page 1 (enter page)?

Can able to find an error in your script. I have seen it completely but failed to locate error.
