With your existing db that you posted on the other thread place this code under the DateStamp command button.
Use the event procedure method that Colin posted
Code:
Private Sub DateTimeStamp_Click()
Me.ClinicalNotes = Me.ClinicalNotes & vbNewLine & Format(Now, "dd-mm-yy_@_h:nn:ss") & " " & Me.CatName & vbNewLine
Me.ClinicalNotes.SetFocus
Me.ClinicalNotes.SelStart = Len(Me.ClinicalNotes)
End Sub
I also just noticed that in your module declarations you only have Option Explicit declared. you should probably have
Code:
Option Compare Database
Option Explicit
The default option compare is binary which means A<>a , etc.
