Can't integrate my shopping cart with my drop shipper

I’m not sure of the ver of Word Press I”m using. I’m using a developer because im not a tech person. I have had a couple of dev working on my site number1donut.com trying to fix the problem. It seems they are not able to integrate woo commerce with my drop shipper scalablepress. The have other customers using woocommerce with there software but for some reason my site is having a problem. I don’t know what type of help you guys offer but anything is better than what I have now, which is nothing.
