Skitter changes my web layout

If I use the following code I have a Blanc, Black square above the body of my web page

<?php if (function_exists(‘show_skitter’))show_skitter();?>

<?php thesis_html_framework();?>

So to get the skitter sideshow to work I add the following code

<?php get_header(); ?>

<?php if (function_exists(‘show_skitter’))show_skitter();?>

<?php thesis_html_framework();?>

Skitter now works at the top of the screen. However I loose all the design features of my website, Colours, Placement of text etc
