I have multiple restaurants with each another value for minimum order price, this is a custom price field in the content type "Restaurants".

I would need to make a rule where the total order amount is compared to this custom price field. If the total from the order is lower, it should redirect and throw a message.

The problem here is that I don't know what entities to use to get access to the custom price field named "field_leveringsprijs".

The event is on payment selection or checkout completion. The actions would be a page redirect and a message which isn't hard to do. I'm just stuck with the conditions 'Entity has field' and 'Data comparison'.

Any suggestions?
