Hey there,<o:p></o:p>
we tried to install this APP on premise (we got the app file from the publisher)<o:p></o:p>

The App installed just fine. Everybody could bet on our local Sharepoint. But when it comes to "calculating the points" a javascript error is thrown. We also have a small office 365 sharepoint and so i installed the app there. The client side javascript executes fine and is exactly the same like on premise.
