QUANTITY RELATED PRICE CALCULATION

[Token]

Hi,

I almost completed a big migration from Joomla 1.5 to 2.5 and VM1 to VM2.

I bought the extension QUANTITY RELATED PRICE CALCULATION but need some help.
http://extensions.virtuemart.net/extensions-virtuemart-2/quantity-related-price-calculation-detail

I need the following price quantities for example. Each price should be a fixed price (not with %) and I need to set this up per product:

1 to 10   = € 29,-
11 to 50  = € 27,-
50 to 100 = € 26,-

How can I do this in the extension? The tutorial doesn't help.
