A question for the group. I have created a series of Google Sheets spreadsheets for a client. Her employees each fill out a timesheet, all of which are linked to a roll-up document that summarizes each week's payroll, etc. Each employee is linked to a separate sheet in the rollup sheet, which then uses some other sheets to summarize the payroll info. In my testing, these all work as designed all of the time. Over the past 3 months, I have had a number of issues where the formulas in the roll up sheets become disorganized. A link to F4 will turn into F187. I solved those problems by using Absolute values (e.g. $F$4) and they do not seem to have reoccured. i have protected some ranges, but since she is the owner, she can override the protection. This past week, two cells were overwritten by what looks like text from another part of the sheet (i.e., F4 and F15 were overwritten by text in F3 and F4). I do have a couple of scripts, but they simply copy the same named range each week and paste it as values on another sheet. My client si not very computer literate and is very awkward in using computers. I am attributing her problems to her inadvertent copy and pasting or moving cells since I cannot find any code or other way of making these changes except by a copy or move and paste or something similar. Does anyone else have these problems or any suggestions? I could do this in Excel with complete confidence that I can protect against any inadvertent changes, but Google Sheets is another beast entirely. We need to use Sheets because her office is distributed and everyone is on-line and not on a LAN. Any suggestions would be appreciated. -------------- next part -------------- An HTML attachment was scrubbed...
