Hi Alexander and Keith
Thanks for your reply, unfortunately, I’m not one step further.
This list seems to be very strange. I created a new DispForm and added dffs, but i did not get the Setup link, so i entered the backend manually and just created a all Fields tab and no other Settings. but i get the same error as in my first post.
Next i copyed the whole list and deleted all fields except the title field. But also get the same error. the console did not show somethig special i think.
Thanks
Ueli
