Issue: You cannot set product details page layout from Category >custom design tab.
For show a static block at product detail and want to set this cms block from admin .Then you need to goto admin>Catalog>Manage Product > select any product and Goto if it design tab and put this code
As product detail page main layout template is view.phtml, and it doesn't render it child block automatically, so on catalog/product/view.phtml add those code block by <?php echo $this->getChildHtml('mystaticblock')?> for render te block.
Note: from admin manage you can only set cms block for one page. Answer Link:
