I have 2 Workbooks located in the same Dropbox folder. One of the Workbooks has a VPA program with an Open Event. In the Open Event, the VPA program can neither Open/Close the 2nd Workbook nor address the Workbook Sheets in commands. Since the Workbooks are located in a DropBox folder, they cannot be addressed like non-DropBox Workbooks (e.g., C:\users\valued customer\DropBox). I have no problem addressing Sheets in the Workbook that contains the VPA program.
