So I have been going in circles, and nothing I try to do seems to work here.
Basically, I have a few very large items in my store that require freight shipping services, I would like to post a message on the cart page if one of these items is in the cart.
I have created a custom Boolean product field called field_freight_shipping. Seems like creating a rule for this should be simple, but finding the right combination of Events, Conditions, Actions eludes me. I am not able to see the custom field regardless of what I do.
