Hi Armin,
The shortcode looks right (although it goes to an under construction site). So it could be redirecting (a 404?) to the home page; I don’t know. So first, did you read the man page on the Single Player and Gallery templates and followed the instructions?
Second, send me a link to the roster table and I’ll take a look.
As for your second question, please start a separate thread for it. (Otherwise how is anyone going to find it?) One topic per thread, please.
