I am trying to create a shopping cart rule where a customer can purchase up to 5 of the same products that are set to a specific attribute at the same price as 1. In my conditions I have selected the attribute ‘sample’ then I want to select if qty in basket is less than equal to 5 to apply the rule. But the quantity in cart option is not available in the drop down menu? Any help would be much appreciated. I have attached a screen shot for reference.
