Need help with product system discount

[rerbe]

Hi All,

 

Can anyone help with the following problem I have.

 

I have installed the Customer Discount contribution that works well although no longer supported. I now have certain products that I do not want included in the discount list.

 

i.e.

 

Johhny buys a TV, cd player and telephone and gets an automatic 10% discount (as per contrib) , but on the same order buys a radio and gets 0% discount (not yet feasable).

 

The default discount is customer specific.

 

Can anyone through any light on this problem.

 

Cheers... <_<
