Make sure you pasted the correct statick block for the slider. Also, go to: appdesignfrontenddefaulthellojynxxtemplatepage and check this file: homepage.phtml ,make sure you have this line:
<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('helloslide')->toHtml()
Be sure your "Home page" has the identifier as "home" and in the "design" has the "layout" as "Homepage".
Hope that helps.
