I visited your site. You have wrong the Layout. You had "2 column Left" and the slider is only in "Homepage".
If you want, you can add a little piece of code for show the slider.
Go to /app/design/frontend/default/hellowear/template/page/2columns-left.phtml
between line 66 and 67, write this code:
<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('helloslide')->toHtml() ?>
Hope it helps!
