Facebook App - Share Button

This is our app: [login to view URL] We have a Share button in our website that used to share the page on this app. FB recently changed this, they recommend using the like button instead, which can be configured to allow people to write their own comments, much like the share button. However, the like button doesn't work with fbml apps, leaving us with no option for sharing for tributefunds Versions1 fb apps. We tried to work around this but the fb comments widget doesn't have the like button any more. I am looking for a solution! I have attached a document which contains screen shots of the process. If you need more info to fix this, please ask.
