Urgent help needed for "Price Factor" Issue

Hi everyone,
I tailor made the zencart to suit my custom made products. The process is that customer pick one product with unit price 10dollar, and then choose different parameters (like style, accessory etc.) and get the final price, i.e. 87dollar. Then they will choose final add-ons, which will add price based on percentage. Zencart make the caluclation in "price factor" (in attibutes controller modeul) based on the unit price only. I need it is based on the final price, here it is 87dollar, instead of unit price 10dollar. I tried to locate where I can adjust the price it loads, but failed. Is there anyone has this issue before? Could anyone help! Thank you soooooooooooo much for your kind help in advanced!

You are expecting this to be "dependent" upon prior selected options pr also called " dependent attributes

ZenCart does not have any support/code for dependent attributes

So, does that mean it cannot be solved? Thanks a lot!!!!

does that mean it cannot be solved?
As stated, there is no dependent attribute functionality

If you post a link to the product some suggestions might be offered
