Your calculation field had a *100 which shouldn't be there and you had a table calculation as percent of total. So i changed it a bit.
Hope this solves your problem

thanks for your quick reply.
The percent results of participated/invited should only apply to the first row (190/400).
But the talbe down values should be the percentages from the first row (the 190), thefore I calculated precent from table down of first row, this works but not in combination with calcualtion (participated/invited to be valid for first row).
Do you think there is another way of calculating it?
