Combinations and quantity discount advise

[justmeagain]

Hi

I am having trouble applying a quantity discount option to some listings.

Example

Item comes in 6 flavours

Offer a 10% discount for buying 2 or more

Offer a 15% discount for buying 3 or more

etc

If I add 2 (or more) Apple - discount is applied

If however I add an Apple AND an Orange (so only 1 of each but 2 in total) - no discount is applied

Is there a solution to this?

 

Any help/advice gratefully accepted.

 

Cheers

S
