Thanks Pete,
Im showing my ignorance in Access - I think VBA is easier in Excel. How to I update the field with GetUser and Now. I tried:
Me![AddedBy].DefaultValue = GetUser
Me![AddedDate].DefaultValue = Now
in the BeforeUpdateEvent in a field in the sub-form but get an error(s). In the sub-form, I do not have a reference to the field in the data table.
