cc4 product percentage OPTIONS

[Guest]

I have purchased Estelle's mod product options percentage.

I have 12 different options that are NOT calculating a running total but only do a discount percentage off of the product.

So if my product is $100 BASE product

EXAMPLE:

Options are:

Select Color

Black = -50%

Yellow = -25%

White = 0%

Select Size

Small = -75%

Med = -50%

Small = -10%

The issue is the option percentages are only being calculated by the base cost of $100 (for example) so if I select option "BLACK" and option "Small" the total price will be negative based on the product price. Total would equal -25.00

I need it to take the -50% and the the next option takes of of the running TOTAL instead of the base product price so that the price does not go negative and is trully dynamic. I cannot have the product pricing go into the negative.

It would like it to do the following:

$100

-50%

running total: $50

then take -75% of the $50 (NOT THE 100)

which would be a total of $28 (or so)

Is this possible? I need some urgent help! Thanks-
