The most likely issue is that you’re using a version of the template that relies on a custom function called TILLER_PERIODPRESET() that is embedded in either the Tiller add-on or the Tiller Labs add-on. Is this function in the first row that says loading in column AD? If yes, is it possible one of the add-ons isn’t running in session you have the spreadsheet open in?
For performance and simplicity, we have stripped that custom function out of the current version of the template and replaced it with a long-ish in-cell formula.
On a related note, in my personal business template, that cell (in AD) is shifted over six cells in and is in column X. This suggests you’re either using an old version of the template or maybe made some modifications?
Curious to hear your answers.
