Changing the default footer

Hi, I'd like to change the default footer in order to show some appreciation for our host. I've looked at a previous thread here but I just can't get the hang of it. This is what I've got:

/*****
**	Changing the default footer
*****
add_action ('catchbase_footer', 'remove_default_footer',99);
function remove_default_footer(){
	remove_action( 'catchbase_footer', 'catchbase_footer_content');
}
*/
function catchbase_asf_footer_content() {
	//catchbase_flush_transients();
	if ( ( !$catchbase_asf_footer_content = get_transient( 'catchbase_asf_footer_content' ) ) ) {
		echo '<!-- refreshing cache -->';

		$catchbase_content = catchbase_get_content();

		$catchbase_asf_footer_content =  '
    	<div id="site-generator" class="two">
    		<div class="wrapper">
    			<div id="footer-left-content" class="copyright">' . $catchbase_content['left'] . '</div>

    			<div id="footer-right-content" class="powered">Works! ' . $catchbase_content['right'] . '</div>
			</div><!-- .wrapper -->
		</div><!-- #site-generator -->';

    	set_transient( 'catchbase_asf_footer_content', $catchbase_asf_footer_content, 86940 );
    }

    echo $catchbase_asf_footer_content;
}
add_action( 'catchbase_footer', 'catchbase_asf_footer_content', 101 );

It works in the respect that I get a new footer below the default, but I'd like to remove the default footer. I guess it's the remove_action part that fails :( Any help appreciated! /Kjell
