WORKBOOK_SAVEAS not working

[Mackeral]

It fails with Error 1004.
The original file name was "Data Entry.xlsm".  After the failure, when  you look at File Explorer, the file has been renamed and it's written date is appropriate.
Is there something about a "Sync" going on here?

Thanks for your help.

You didn't provide the code that you are trying to use.

Don't know what happened. I definitely edited the code into the Post, and don't understand why it didn't show up.

Here's the code

WORK_BOOK.SaveAs _
            FileName:=FileName, _
            FileFormat:=File_Format, _
            CreateBackup:=False

I, personally, need to see more code than that.

Variables mean nothing to me, and excel, if the values of them are unknown.
