Help with Facebook App Inviter...

You should be available through msn/yahoo/skype after accepting your bid. We have an small application which uses Iframe, we setup an inviter script to send invitations after somebody adds the script. The script is showing a blank page after you select the friends you want to invite. We'd like somebody experienced in facebook applications to take a quick look and let us know the solution. We want to add a shareit button to the application page as well.
