I read the user manual saying that the discount may be expressed in dollars or percentages. but when I tried to use percentage (by typing "10%"), the value is not allowed in the field.

Is discount by percentage not working or am I typing incorrect value in the field?

I'm trying to setup a product discount. After product setup is completed, I clicked on "Discounts" tab on the same page (page title: Manage Product Quantity Discounts - product name".

I filled "Quantity From" to 5, "Quantity To" to 10 and "Product Price" to 10%, and pressed "Add Quantity Discount". An error message "Enter a number" showed up next to "Product Price" text field. If I enter "10" instead of "10%" that would be a discount by dollar amount....

I installed "Smith.BuyNow03.06.00-DNNS.zip"
