Quantity Discount Affect Attributes?

[Ficilya]

I'm new with zencart, i think, i just found a bug with quantity discount and attributes price..

Example :
T-shirt => Price $50
Red +10
Blue +20

Quantity Discount :
2-3 = 10%
4-5 = 20%

If i add 2's Normal shirt to cart the price now will be $90 and i thinks it's correct..But when i add 2's Red shirt it's price now $110 => (50-5)*2 + 10*2
And I thinks it's wrong..

I want the Final price will be $108 =>(60 - 6)*2, i want the attributes will be discounted too..I know there is Attributes Qty Discount, but it doesn't what i'm looking for..

Are there any guide to do this?
I know PHP and I can code it by myself if i know the clue from you..

Sorry for my poor English..

Try Pricing your product by attributes

No base price in product setup screen - - check the priced by attributes box
Change the attributes and enter the actual price

Thanks for your response..
I have set the product price to zero, and I have set the attributes to actual price..
Example :
Attributes => Red $60 , Blue $70
It's still doesn't work..

Is this a bug or not?
I think i need to modified something in function_prices.php, but i dont have any ide, what part or line i need to code..i've been spending about 1month to trying to solve this problem..
Thanks

Are you saying you have the Quantity set to:
2-3

Did you check the priced by attributes box in the product setup screen

Oh yes, i forgot that stuff..Now it can work..
But, My store is using same attribute in all product and every product's price is different each others..

Any idea how to do this without set attributes price in every products..
