Hi all,

I am now working hard on debugging the NullReferenceException Error.

While I checking the Error message, I saw there are a "[2]" in the message.


Is it just simply alert me this is the second record of field("TotalPages") and field("PageNo")?

Or it is refer to the i-th index of the TotalPage[i] and PageNo[i], i.e. 3rd record of the field(array[0] refers to the first record, so array[2] should refer to the 3rd record)?


Thanks for clarification in advance!
