title: Google Sheets Sum values from ALL sheets in a workbook
body: <p>So assuming I have a Sheets Workbook with random sheet names, "Bob", "Sally", "Billy", "John" or something similar that isn't sequential. And I have another sheet called "Totals". How can I sum the values from a particular cell, say "H4" from all of them? Specifically if I added new sheets after I created the formula without having to change the formula every time?</p>
