Don't want Attributes to use Sale price

http://www.marybethcarlson.com/catalog/index.php?main_page=index&cPath=3

I'm on the newest zen cart and am selling cds on my site

cd = $14.95 (attribute option with $0)
cd download = $9.99 (attribute option with -$4.96)

I put a sale on the cds of 20% off. This brings the cds down to $12 - great!

But my download is now $7.04

Where do I need to look in the code to have the attributes take off of the products base price only??

Thanks!

You mean in this case 20% should be applied only to cd=$14.95 and not cd download=$9.99?

$9.99-$9.99*(.20)~8
and not as
(14.95-14.95*.2)-4.96 ~ 7

What it looks to be doing it the 14.95 is getting the 20% off and then the attribute is doing the -4.96 off of that instead of the normal product price :)

12-4.96=7.04

I need it to always look at the normal product price when doing the minus

Thanks!
