How do I get my Product Forms and 'Send What You Have' options to show up for my products with options?

There is an option in the system settings that will allow that information to display, but it will turn off the newer, more graphically pleasing view of the product Options. Once you have logged into the Rain system as an Administrator (your login link should look like 'yourwebsitename.rainadmin.com/admin'), on the far right side of the blue Admin Toolbar, click the gear-shaped button. In the drop-list, click on Settings > Website Settings > Products, you will see a setting for Enhanced Product Options View a short way down the list. Change the setting to On, then scroll to the bottom of the page and click Save.
