display custom order fields in a checkout pane
I have added a custom field in orders and I can view and edit. I want to display this custom field in checkout panes, so users can fill them. but by default there is no relation between fields that we can add to checkout panes and the fields that we add to orders.
How can I display fields that I add to orders in the checkout form?
Commerce Fieldgroup Panes
I think the easiest technique is [Commerce Fieldgroup Panes](http://drupal.org/project/commerce_fieldgroup_panes). Screencast at http://www.commerceguys.com/resources/articles/257
Thanks a lot, this helped me very well.
