Shopify coding

I've run into an issue with the buy button on Shopify. After connecting with Shopify support they've advised me "We have brought up the issue of the missing buy button and mislinking buy buttons to Shopify support, and they have let me know that the code has been manually changed. The code on every product description has been affected in these ways: The link to the buy button is incorrect, The buy button has been completely removed." I'm looking for immediate assistance. The buy button is being applied to a [login to view URL] site but does not even show the buy buttons on the actual shopify site. Check it out... [login to view URL]
