Fix Facebook invite functionality - repost

I've had another freelancer develop a script for inviting friends via Facebook to my site. It looks like this: [login to view URL] You can access it by going to [login to view URL] and clicking this button: [login to view URL] It is based on functionality from [login to view URL] that does the same. However, it's not fully functional: - When I open it and click "Invite" (with all friends selected), nothing happens. It should work like this: [login to view URL] If e.g. 250 friends are selected, it should include the first 50 of these in a "send request" dialog. Once user sends request, the next 50 should be shown so request can be sent to them. The reason for this behaviour is that you can only send 50 requests at a time with the Facebook API. - This works part of the way on [login to view URL] but for some reason, it doesn't work when you click on the front page If you can fix this, I have several other Facebook API related jobs. Please post links to previous Facebook API related projects you have done.
