I'm posting this for a user who sent me the following query, which I've
inserted below as submitted to me:

"Hi ,

Don't know if you know any VBA but I have a problem that I haven't been able
to resolve. I don't know any VBA but I can usually cheat by looking
something up via google or recording a macro and transferring and altering
parts of the code to do what I need it to do. But I haven't been able to
figure this one out:

I have a footer macro that I set up to include the "last author" and "last
modified" items rather than the current date/time and the original author.
The problem with my footer is that it doesn't update these items
automatically when I save. It will only update if I re-run the macro to
insert the footer. (This is the same problem as with using the regular
pathname footer in Excel - which doesn't update when you use save as and save
a file with the pathname in the footer to a new location.)

Sub Footer()
'
' Footer Macro
' Macro recorded 3/26/2007 by atao
'

ActiveSheet.PageSetup.LeftFooter = "&8Last Modified by " & ActiveWorkbook. _
BuiltinDocumentProperties("last author").Value & " " &
ActiveWorkbook. _
BuiltinDocumentProperties("last save time") & Chr(10) & "&Z&F\&A"

ActiveSheet.PageSetup.RightFooter = "&8&P of &N"

End Sub


So, I am either trying to find a way for those items to auto-update as does
current date and time (when you use &[date] &[time] (which I have a feeling
can't be done for Builtin Document Properties or have the macro re-run
automatically upon saving. I found something called "OnAction" property that
may do the trick when save is pressed but I actually don't know any VBA so I
thought maybe you would be able to help me?"
