As this is the first time using rules for me, maybe I am doing something wrong. I want to set the product price to 0 if no price is set. What I am doing so far is this:
Event is "before saving a commerce product" Condition is "Data value is empty" Action is "Set a data value"
But there is just nothing happening and I still get an "no price set error" when I try to save a product without a price. Anyone knows how to do it right?
