You shall probably have some code for Before_Close event, but exact implementation depends on mechanism used for spinup/doen button action, so attach a sample workbook. Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.

After brief look on the file, I think the appropriate place will be Workbook_Open event handler (in ThisWorkbook code):

Private Sub Workbook_Open()
On Error GoTo errhandler:
Rows("18:92").Hidden = False
Exit Sub
errhandler:
MsgBox "There appears to be an error in Workbook_Open procedure. Please contact your administrator", vbCritical
End Sub
