Item Price Showing incorrect

[twacking]

Hi,

 

I am setting up a store: http://www.edroche.com/store , which sells art prints. Most prints are available in different sizes and framed/unframed. My problem is that if you select an item for $30 , the other option myabe $15, then the total show $45 and not $30. It is adding both together. In cases where only one item is available it is doubling the price. I have removed all shipping options and still nothing.

 

Please help!
