I just have a quick question. I have a tab called MASTER and I want to
have a message box pop up whenever someone clicks on this MASTER tab
warning them "Changing these two dates, changes all dates in the
headers of the Excel Worksheet." I believe there is a message box that
shows a circle with an X in it and I think you use +vbCritical, but I'm
not positive. Any help would be greatly appreciated.
