I can't reproduce the error with the file, on the contrary I get other errors when I run the code.
If I open the file I get an RTE 9, I looked at the code and found that a sheet "Sheet1" is accessed which is not in the file.
I found the Validate button in the last sheet, when I run the code I get an error "Error found in the sheet", I click Ok and sheet "Errors" is shown with some data.
I think the best way is to contact the developer of the file, because the code and the worksheets are password protected.
I've seen other code that executes
ChDir FolderName
and FolderName is "" at this point which causes the RTE 76 you mention. FolderName is generated from another variable "path" and this variable is generated from
path = DefPath & uploadFileNm
where
DefPath = Application.DefaultFilePath
and
uploadFileNm = a generated string from Date/Time and a cell in another sheet
I think the issue is that FolderName is generated when you e.g. click other buttons, but if you click the Validate button the FolderName is empty and causes the issue.
Send this the developer of the file, maybe it's helpful.
Andreas.
