Not an embeddable url?

Site URL: http://www.flipflopsvb.com

I’m trying to embed or frame some content on a page. I’m creating a raffle to help save a local business. I created the bid on biddingowl and now and trying to get the content to display on a page In square space. Can someone help me embed this code? I’m getting that “not embeddable url” error.

The Url  isn't embeddable with Squarespace.  SS is not as forgiving when it comes to URLs as say Facebook, can't use the embed code from Youtube either. So that leaves linking it, use a button or a click thru  image. The URL will work then.
