Please help! I'm completely lost in creating Magento Admin Grid. It's been a week now.
I have created a module coming from this tutorial http://ecommerce.eglobeits.com/blog/magento-admin-module-development-with-grid-and-tab/. The problem was, the grid won't show up. I have successfully created database table via install script.
Question:
How do I make the grid work?
Can you spot the problem?
These are the codes.
