Glide is telling me that there is missing data on my sheet. I see no missing data. When I resync the sheet I lose a bunch of components. Help! ---

This usually indicates that you have modified the sheet and columns that were there before are no longer there. Did you move columns or delete any either manually or by a formula getting overridden? ---

Do you have a duplicate/backup copy of the app? If you do, make an additional copy before you open that one. If not I don’t know what to tell you. Maybe one of the Glide team can advised you. @Mark ---

Yes I duplicated the app. Everything is fine as long as I don’t reload. I tried restoring the spreadsheet to an earlier version but still no luck. I will keep experimenting. Thanks ---

You duplicated the app and did not change the spreadsheet at all, and then you saw this dialog? ---

@Todd_Peterson Could you share the app for which you saw the message? ---

Thanks Mark. I cleaned up my spreadsheet And redid the app and all seems well now. I must have deleted something.
