I am having difficulty getting the value from textbox 1 and textbox 2 to combine and display in a textbox3 on a userform. Textbox1 and Textbox2 are locked, the values are dynamic and auto-filled from radio button controls. I have tried the following but it doesn't display the combined result in textbox3 and I think it's because the values in textbox 1 & 2 are the result of counter controls on the radio buttons. See image link.
Private Sub TextBox3_Change()
textbox3.text=Textbox1.text & Textbox2.text
End Sub
