Help with product attributes !!

[epicflyers]

Hello everyone,

I am trying to set up a printing company with presta shop. I already created a product for business cards and under that product I added the attributes that i need such as quantity (1,000 5,000) artwork (design needed, supplied) etc (i did them all seperate).. The problem is that I need the price to change when you select a different quantity. I already checked the impact on price increase and I added the amount but it doesnt update it on the cart or when you select the product. the price doesnt change at all. can anyone help me fix this?

thanks in advance!!
