Answer 1

I am trying to convert a Spreadsheet from Excel to Google Sheets. Most formulas have worked as expected, with the exception of this formula:

=SUM('J Slater:Job Sheet'!C6)

I am using it to sum a specific cell over a range of sheets this formula allows sheets to be added between the range an also be added to the sum cell without any change to the formula. I can't find a way of replicating this in Google Sheets.

Thank you for adding this. My company will not allow for me to use add ons, so I cannot add the UTIL that is usually used for this. However, when I tried this script, it did not work entirely. It filled a cell with a running string of all of the values from the tabs, but did not give the sum. Please check the script for accuracy.
