Hi,
The "next" button is added in the "checkout | step" view and you place your module in the "checkout | cart".
So, you can:
- Modify the "checkout | step" view in order to move the "next" button (but at the top of the page if you want something nice).
- Display your module in the view "checkout | step" and not in "checkout | cart". So the module can be placed under the "next" button.
