add a sponsor/grab button sidebar

I am using Fancy theme on my blog: KatyConfidential.com, and I want to add another sidebar for sponsors/grab buttons. It would be great if I could just have another column of the 3 widgetized blocks. I am new to this but here is what the functions.php says (I took out the specifics):

if ( function_exists(‘register_sidebar’) ) {
register_sidebar(array(
‘name’ => ‘Yellow’,
‘before_widget’ =>
‘after_widget’ =>
‘before_title’ =>
‘after_title’ =>
));

register_sidebar(array(
‘name’ => ‘Green’,
‘before_widget’ =>
‘after_widget’ =>
‘before_title’ =>
‘after_title’ =>
));

register_sidebar(array(
‘name’ => ‘Pink’,
‘before_widget’ =>
‘after_widget’ =>
‘before_title’ =>
‘after_title’ =>
));

}

Thanks!
