a bit more information regarding the problems i am having with the attributes...

i have item A at a length of 20" with a base price of $20

then i have a 50% sale so the product price is $10 on sale

i have added an attribute of 22" and want to sell this at 10% more

so i have marked the price factor as 1.10

the following occures on the on the product page...

on the choose length dropdown box that i have the item shows a price of $11 for the 22" length (which is the $10 sale price plus the 10% add on) which is correct!

BUT when i add to cart and go to check out... it calculates the 22" price incorectly.

what it does is take the original presale price of the 20" add to it10% and then it adds the sale price of the 20" on top of that

meaning

the 20" = $20 original price presale
1.10 x $20 = $22
$22+$10 = $32

the 22" is $32 in the shopping cart instead of $11

was i clear on this???
