Copy cell to text box

[Walczakts]

I'm sorry in advance if the answer is painfully obvious, but I am not very knowledgeable when it comes to macros.
I am attempting to copy the contents of cell "C2" and paste it a line above the first line in "textbox2" or a line below the last line in "Textbox 2" while keeping the text that is already in the textbox with the push of a button. Is this possible to do with a macro, if so how? Hopefully my question makes sense and one of you excel guru's can help out.

Hi. Ive used a worksheet change event macro but you could assign something similar to a button if you want.

Private Sub Worksheet_Change(ByVal Target As Range)

Dim rng As Range

Set rng = Intersect(Target, Range("c2"))

If Not rng Is Nothing Then
    If rng.Value <> "" Then
        With TextBox1
            .MultiLine = True
            .Value = rng.Value & vbLf & TextBox1.Value
        End With
    End If
End If

End Sub

You right click on the sheet tab and press view code. Insert the code there. Then overtype C2 and see if it works. May need to change the name of the textbox in the code.
