Hello, I am trying to replicate the reinforced concrete section properties worksheet, but I am getting an error message. The error message is, "This array index is invalid. The index must be an integer, not less than origin, and not greater than the last element." I am strictly following the worksheet for this example and it is not working. Any ideas as to why this is happening? Worksheet is attached!

Where "i" is a literal subscript (Ctl+-).
You need to chage it to:
Where "i" is a matrix index ([).
