Multiply by user field?
Is there a way to make a rule to multiply the price of a product by a user field ("field-markup")? I'm looking to provide different markups/discounts on a per-user basis. I can see my field-markup in actions -> multiply by amount -> amount, but it gives me this error:
Data selector site:current-user:field-markup: for parameter amount is invalid.
I currently have the fiel-markup set to a "Price" type.
Should this be able to work?
