Problem with options in a product

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.0

Maybe I should be post in other forum. Sorry but I don't know where.

The problem is:

I have a "product A" with 3 options product (B, C, D). The "A" product price is -20€. The customer choose every option, with a total price less 20 euros of the product price. Example:
A= -20
B= 100
C= 100
D= 100

Total would be: 280

The problem is when this customer remove a option product in his cart. The discount (-20 euros) remains, when it should remove the "product A".

Because if the customer don't buy the 3 products, he shouldn't have a discount 20. In the same example: if this customer remove "B" product, the total price should be 200, not 180 .

Can you fix this behaviour?

Thanks for your software

Perfect!!!

I'm glad to get this product (Hikashop), and this support!. All options are possible... ¡wonderful!

Thank you very much.
