Question : Simple VB 2010 function

In Visual Basic 2010, i have a list box full with a list of data, and I also have a Group box and a button. I would like to what code I need to put into the button to enable the selected field from the listbox then appear as text in the group box.

If you need any more information please feel free to ask.

Any help would be greatly appreciated

Ive attached a picture below.

If you think it will be easier to use a textbox , im open to suggestions.
