How to use Block Price and Block Unit Price for Point Price Breaks?

Hi,

I have a pretty simple requirement to price an item based on base price and price per units. The item is priced as follows:

0-29 units = $675 (Total price)

29-99 units = $30.75 per unit

99 and up = $30.50 per unit

I tried setting up the following:

Line Type: Price Break Header / Price Break Type: Range / Application Method: Block Price

Value From: 0 / Value To: 29 / Price:675 / Application Method: Block Price

Value From: 29 / Value To: 99 / Price: 30.75 / Application Method: Break Unit Price

Value From: 99 / Value To: 999999999 / Price : 30.50 / Application Method: Break Unit Price

The problem with this is that if I have 31 units, then it adds $675 + 3*30.75.  I want it just to price anything between 30-99 as (# units * 30.75).
