attributes plus base price, Quantity discounts

Some of my products need quantity discounts. I need a percentage discount off the price plus the added attributes when a certain amount is added. I followed the zencart tutorial shown below.

How do I add quantity discounts to my products?

Admin -> Catalog -> Products Price Manager

• Select the product
• Edit
• click the "add 5 blank discounts" button
• fill in the details
• Update

This just added a visual, but did not total up the discouts. I know where to add the discounts for just the attributes but not the base price and attributes.

Can anyone tell me where I can do this

Thanks jason

Sorry my mistake. The change above does make a change to the base price. So I guess I apply the same to every attribute to in effect add an overall percentage discount.
