Hi, there

I have the nested list below:

`[[A,1],[B,2],[C,3]]`

If I want to get the sum of the second values of each list, the formula I use is:

`List(List("A",1),List("B",2),List("C",3)).FormulaMap(CurrentValue.Nth(2)).Sum()`

The thing is this formula returns **the right result** but with the error message bellow.

Am I doing something wrong? Is there another way of doing this?

I’m assuming it’s a bug. For instance, if I used .count() instead of .sum() you don’t get the same error message.
