I had done this in the "Property sheet". I used Access on a regular basis, a hundred years ago, but have been away from it for so long I think I have forgotten everything, lol.
The Exact Error is:
Microsoft Access cannot find the object '[Re-Certification_Date]= DateAdd ("yyyy",1,[Certification_Date]).'
If '[Re-Certification_Date]= DateAdd ("yyyy",1,[Certification_Date])' is a new macro or macro group, make sure you have saved it and that you have typed its name correctly.
There is no number associated with the error.
Thanks again!
