I am currently working on a gift voucher system using the Commerce & Coupon modules. I have this working to a degree using line items.

I am trying to add a field below each product on the checkout page to allow the customer to enter a personal message. I can get this working on the cart page using the Commerce Line Item Cart Form module. How ever if I move this to the checkout page when I click save it actually submits the whole form and goes to the next stage/pane of the checkout.

Has anyone any suggestions on how to do this as I don't want the customer to do this on the product detail page?

Thanks
Robert
