In Access, I have a form in which there are three textboxes.
I am trying to update a textbox called *tbxCombinedName* with a combination of both:

* textbox *tbxLastName* (person's Last Name)
* textbox *tbxFirstName* (person's First Name)

My question is: what textbox property do I use, so that as I am typing text in *tbxLastName*, the CombinedName textbox is updated **immediately** and thereafter saved in the table *Contacts*.

On [Microsoft's website](http://msdn.microsoft.com/en-us/library/office/aa211341%28v=office.11%29.aspx), I have found that the step processes when typing in a textbox are as follows:

**KeyDown → KeyPress → BeforeInsert → Change → KeyUp**

I've tried using the OnChange and OnKeyDown properties, but to no avail. Which property, combined with what code, will allow the update-as-you-type action to work?

This is what I wrote earlier, which didn't work:

```
Private Sub tbxLName_change()

Dim lastName As String
Dim nameCode As String

lastName = tbxLName.Value
Debug.Print lastName
nameCode = tbxNameCode.Value
nameCode = lastName
Debug.Print nameCode

End Sub

```

Thanks for all your help in advance.
