Looking for someone to fix custom options so it applies percentages correctly.
Currently custom options just add the percentage to the base price.
For example buy 100 for $100 add a custom option (blue) for 10% price = $110
But if you change the quantity to 200 with custom option blue for 10% it only uses the base price and returns $210 instead of $220. So I need the custom options to update based on changes to the quantity.
This is a Magento 1.4.2 site, I'd like any mods to work with upgrades.
