Access is personal. Each visit, every switch you move and every file you open is logged for the company.
Read it, tell us who is accepting, tick the box. You will see it once; a copy with your acceptance is kept by both sides.
One engine, three sheets you see: the control panel sets the switches, the fleet runs 120 months behind the page, the Global view shows the result. Green figures are live.
Every input and output the site uses is a defined name in the workbook. Keep them on the right cells when you rework the model; the upload check tells you if one is missing.
Changing the text starts a new version: every room set to "tick box" accepts it again on its next visit. Have your lawyer review it.
