Here are a few thing that I noticed, hopefully this will help you out.
1. The php file does not have any opening tag, and it also has javascript, which should go in the .tpl files.
2. You need to add a line of code to home.php that will include the great_products.php file. For example:
Code:
include "./great_products.php";
3. You will also need to add your table to the $sql_table array in config.php.
You will probably still have some errors, but this should at least get headed in the right direction.
