hi, just met a problem on how to set price by different attributes.

like original price 10, size L +10, size XL , +20?

i am using 1.39h,

i tried to input digit 10 in the box next to default "+" box, the box under "Prices and Weights",

and it turned as prefix price 10, and an unknown discount generated?

already searched the forum, but no satisfying answer,

thank you in advance!
