formula to show when values where last updated?

[brad]

does anyone have a formula for when a file is last updated
(saved changes), kinda like viewing the properties screen
but in a cell?

Hi
use the following UDF (only on workbook level):

Function DocProps(prop As String)
application.volatile
On Error GoTo err_value
DocProps = ActiveWorkbook.BuiltinDocumentProperties _
(prop)
Exit Function
err_value:
DocProps = CVErr(xlErrValue)
End Function

and enter in a cell
=DOCPROPS("last save time")
(format cell as date)
