Joomla + SMF + Tinyportal: Changing the theme/Using Shoutbox

[darkstar3]

I don't understand why things like

Code Select Expand


<a href="', $scripturl, '?action=search;advanced">', $txt['smf298'], '</a></span>

and

Code Select Expand


<div style="text-align: center; margin-top: 5px; " class="smalltext"><a href="',$scripturl,'?action=tpmod;sa=shoutbox;shouts='.$context['TPortal']['show_shoutbox_archive'].'">',$txt['tp-showshouts'],' ',$context['TPortal']['show_shoutbox_archive'],'</a></div>';

work how they shoud (with using scripturl! ) and things like

Code Select Expand


          echo '<input style="margin-top: 4px;" class="smalltext" type="submit" name="shout_send" value="'.$txt['shout!'].'">';


not 

Ok, then I have to wait for a answer from Joomlahacks.
But in a big community like the one from Joomla I don't get as much help as here
