default Shopper Margin concatenated to other shoppers? why

[scorp2000]

Hi

im using latest version of VM

currently im using three shopper groups to set different prices

default, shopperA, shoppperB

then i create three different margins at taxes & calculation

default = 20%
shopperA = 15%
shopperB = 10%

and then assign shopers groups one by one


i want to set individual percentage at products . but VM add default % to shopperA & shopperB as well means shopperA margin display 35% and ShopperB 30%


and guest price display without margin.

VM version: 2.0.26a
joomla: 2.5.16
Chameleon: 2.36

Simple maths.  Calculation rules are additive, and "default" means apply to all shoppers who are logged in. So if they happen to be in your shopperA group then for that group 15% will be added to the 20% applied as default, giving 35%
