Userform Listbox update with Option button

[ThomasOES]

Hello
I'd like a userform listbox to update while the userform is visible. I'd like to click on an option button and the listbox below the button then update the list of items based on which option button is selected.
Something like

if optionbutton 1 = true then listbox.list = Array("Iron", "Copper", "Nickel")
if optionbutton 2 = true then listbox.list = Array("Titanium", "Cobalt", "Zinc")

Seems the userform would need to "refresh" based on option button choice.

Thanks for any help
Tom

You could use the UserForm.Repaint method I believe.
