    1. COit seems like the error is pretty straightforward. the required argument type is Mage_Core_Block_Abstract, but you are passing it a boolean. it appears to be finding your class ok, but it has this error. you sure the tutorial and your mage version are compatible? post the code arround line 22 in your controller for any further help...

    2. COYou are correct in that it is not finding the Block. `$this->getLayout()->createBlock('awesome/adminhtml_report_simple')` is returning `false`. You'll need to post your `config.xml` and `Super_Awesome_Block_Adminhtml_Report_Simple` code, and confirm that the filenames/paths are correct before we can help you.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
