Quantity Break Price

HI

I need to set up a range of quantity break prices for an item where depending on the quantity ordered a flat rate price is used.

For example

1 -200 = 16 

201 - 500 = 26

501 - 1000 = 40

so if a customer ordered 2 or 99 he would still be charged just 16 and if he ordered 350 he would be charged 26

I have tried using quantity break with  price break header as line type, Point as Price Break Type and block price as application>
This displays the unit price as 16 /200 * quantity for the first quantity break

For example

2 units has unit price of 0.16 but extended price of 16

200 units has a unit price of 0.08 but extended price of 16
