Problem with forum source code

[tomekgp]

Then.
I must insert into my forum source code , code from Gemius Statistics :

<!-- (C) 2000-2009 Gemius SA - gemiusAudience / ver 11.1 / strona_glowna_serwisu-->
<script type="text/javascript">
 <!--//--><![CDATA[//><!--
var pp_gemius_identifier ='1vaaqGbwo10StnPGJBxYtnYY.Mf1eZgD_CVNrGBaM43.q7';
//--><!]]>
</script>

I go in admincp to Styles & Templates, edit template footer and then insert code above .
I also tried to edit other templates...

After edit, Gemius didn't work.
In forum source code I see only:

<script type="text/javascript"> <!--//--><![CDATA[//><!]]> </script>

Where is the rest of this code ?
It isn't only problem with this code. I saw that all lines that are commented have problem like that - forum don't showing commented codes. And this is the main question - why ?
Have the same problem with TradeDoubler code must to insert for verify my page...
