I actually have a much simpler solution. You need to pass the (sub)form object along to the main basAudit sub.

Now, becuase the subform is the one initiating the command, it will be passed along to basAudit sub instead of the ActiveForm (wich is the main form, not the subform).

Modify the basAudit module as followed:

Sub AuditChanges(IDField As String, UserAction As String, UsedForm As Form)
    On Error GoTo AuditChanges_Err
    Dim cnn As ADODB.Connection
    Dim rst As ADODB.Recordset
    Dim ctl As Control
    Dim datTimeCheck As Date
    Dim strUserID As String
    Set cnn = CurrentProject.Connection
    Set rst = New ADODB.Recordset
    rst.Open "SELECT * FROM tblAuditTrail", cnn, adOpenDynamic, adLockOptimistic
    datTimeCheck = Now()
    strUserID = Environ("USERNAME")
    Select Case UserAction
        Case "EDIT"
            For Each ctl In UsedForm.Controls
                If ctl.Tag = "Audit" Then
                    If Nz(ctl.Value) <> Nz(ctl.OldValue) Then
                        With rst
                            .AddNew
                            ![DateTime] = datTimeCheck
                            ![UserName] = strUserID
                            ![FormName] = UsedForm.Name
                            ![Action] = UserAction
                            ![RecordID] = UsedForm.Controls(IDField).Value
                            ![FieldName] = ctl.ControlSource
                            ![OldValue] = ctl.OldValue
                            ![NewValue] = ctl.Value
                            .Update
                        End With
                    End If
                End If
            Next ctl
        Case Else
            With rst
                .AddNew
                ![DateTime] = datTimeCheck
                ![UserName] = strUserID
                ![FormName] = UsedForm.Name
                ![Action] = UserAction
                ![RecordID] = UsedForm.Controls(IDField).Value
                .Update
            End With
    End Select
AuditChanges_Exit:
    On Error Resume Next
    rst.Close
    cnn.Close
    Set rst = Nothing
    Set cnn = Nothing
    Exit Sub
AuditChanges_Err:
    MsgBox Err.Description, vbCritical, "ERROR!"
    Resume AuditChanges_Exit
End Sub

Change the AfterDelConfirm sub as followed:

Private Sub Form_AfterDelConfirm(Status As Integer)
    If Status = acDeleteOK Then Call AuditChanges("Site", "DELETE", Form)
End Sub

And last, change the BeforeUpdate sub as followed:

Private Sub Form_BeforeUpdate(Cancel As Integer)
    If Me.NewRecord Then
        Call AuditChanges("Site", "NEW", Form)
    Else
        Call AuditChanges("Site", "EDIT", Form)
    End If
End Sub
