I am trying to add attributes to a configurable product where the quantity is the quantity of another attribute multiplied by a particular number.  I submitted a How to Question about this to ResponsAbility and the response was to add an expression in the quantity attribute of the attribute properties.  I did this and it worked perfectly.  I then tried to add another attribute to the product and now the quantiy is no longer being calculated.  I even removed the new attribute and still the quantity is not being calculated.  What can I look for to cause this calculation to no longer occur?  It's still in the quantity attribute of the attribute properties.
