Why does activate excel sheet 2 via ACTXSERVER return an error ?

I am trying to activate sheet 2 of excel by using actserver, but it will return an error when I run my code. Can anyone explain what I had did wrong for my code?

your explaination will be greatly appreciated. My code is as below

 e= actxserver('excel.application');

% Insert a new workbook.
eWorkbook = e.Workbooks.Add;
e.Visible = 1;

% Make the sheet active.
eSheets = e.ActiveWorkbook.Sheets;

eSheet1 = eSheets.get('Item', 2); % Want to edit 2nd sheet in workbook
eSheet1.Activate;

% Below is the error shown
% Error using Interface.Microsoft_Excel_16.0_Object_Library.Sheets/get
% Invoke Error, Dispatch Exception: Invalid index.

Besides, i am trying to write a set of data to excel with my own layout (merged cell, border line, colomn color), can I know where can I get the example or tutorial to use actxserver to write data to excel? Thanks in advance.

Regards, Lily

This is an interesting question :-)

At the moment as outside observers, we do not know that the workbook has more than 1 sheet after the Add is done.
