Hey Kai,
The problem, which I couldn’t find a solution for in that post, is that when I add that function, it creates an error with the calculations.
That is, in each column the user enters a number, then the bottom row displays the total of the numbers in each column (sum, not frequency). This calculation returns an error when I add the repeat groups.
Do you have any ideas or could you point me in the right direction for some more info on how to work aroun dthat?
