Hi,
Try tis bit of code in the "Thisworksheet" module.
When the user close the workbook it should be save to the specified drive.
Code:
Private Sub Workbook_BeforeClose(Cancel As Boolean)
Application.DisplayAlerts = False
ActiveWorkbook.Save Filename:="C:\Users\laura\Documents\Excel\ExcelFiles\David.xlsm"
Application.DisplayAlerts = True
ActiveWorkbook.Close
End Sub
