Getting Group Review App Working!

Hi Si Team

I have bought and installed the group app:

https://stackideas.com/apps/item/3341-group-reviews

You can find it here on my site:

https://www.finalbug.net/groups-learn-post-production-socially-fcpx-and-more/groups/26-fcpx-not-pro/apps/238-reviews/form

But can not get it working either logged in or not logged in.

I have it run up in the applications menu both in the ES side bar and the ES header drop down menu.

I can access it and type a review but pressing “submit” does nothing!?!

What am I missing? U could not find any documentation...

please advise thanks

Paul
