Something like:

Private Sub Form_BeforeUpdate(Cancel As Integer)
Dim ctl As Control
Dim changed As String
For Each ctl In Me.Controls
  ' only check the text boxes and combo boxes on the form
  If Left(ctl.Name, 3) = "txt"  or Left(ctl.Name, 3) =  "cbo" Then
    If ctl.OldValue <> ctl.Value Then
     call logit(mid$(ctl.Name,4),ctl.OldValue,ctl.Value)
    End If
  End If
Next
End Sub

Sub logit(ControllName As string, OldValue as String, NewValue as String)
Dim strSQL As String
strSQL = "Insert into Audit (FieldChanged,OldValue,NewValue,CDate)"
strSQL = strSQL & "  select '" & FieldChanged & "','" & OldValue & "','"
strSQL = strSQL & NewValue & "',Date()"
DoCmd.SetWarnings False
DoCmd.RunSQL sqlstring
DoCmd.SetWarnings True
End Sub
