Audit VBA not working

[RosaCat]

Hello,

I have issues with the Audit table. Here's the Module VBA:
Option Compare Database


Const cDQ As String = """"
Sub AuditTrail(frm As Form, recordid As Control) <-----------------Debug Highlights this
'Track changes to data.
'recordid identifies the pk field's corresponding
'control in frm, in order to id record.
Dim ctl As Control
Dim varBefore As Variant
Dim varAfter As Variant
Dim strControlName As String
Dim strSQL As String
On Error GoTo ErrHandler
'Get changed values.
For Each ctl In frm.Controls
With ctl
'Avoid labels and other controls with Value property.
If .ControlType = acTextBox Then
If .Value .OldValue Then '<--------------------- Debug makes this statement font red.
varBefore = .OldValue
varAfter = .Value
strControlName = .Name
'Build INSERT INTO statement.
strSQL = "INSERT INTO " _
& "Audit (EditDate, User, RecordID, SourceTable, " _
& " SourceField, BeforeValue, AfterValue) " _
& "VALUES (Now()," _
& cDQ & Environ("username") & cDQ & ", " _
& cDQ & recordid.Value & cDQ & ", " _
& cDQ & frm.RecordSource & cDQ & ", " _
& cDQ & .Name & cDQ & ", " _
& cDQ & varBefore & cDQ & ", " _
& cDQ & varAfter & cDQ & ")"
'View evaluated statement in Immediate window.
Debug.Print strSQL
DoCmd.SetWarnings False
DoCmd.RunSQL strSQL
DoCmd.SetWarnings True
End If
End If
End With


Next
Set ctl = Nothing
Exit Sub


ErrHandler:
MsgBox Err.Description & vbNewLine _
& Err.Number, vbOKOnly, "Error"
End Sub

This is what I entered into the form "Before Update":

Private Sub Form_BeforeUpdate(Cancel As Integer)
Call AuditTrail(Me, ContactID)
If MsgBox("Do you want to save the changes?", vbYesNo) = vbNo Then
Me.Undo
Cancel = True
End If
End Sub

I don't know VBA well enough to figure this one out. Please Help!

Should probably be

If .Value <> .OldValue Then
