Insert text based on userform selection

[Ted]

I have a userform with 3 listboxes.

Can I use the INSERTEXT feature or does it have to be done in vba as the
userform is vba

You can't populate listboxes or comboboxes with insert text. you need to use
VBA code and be familiar with different events for each control in order to
write yoru code in a proper event.
to populate a listbox you can use :
Listbox1.Additem "Text 1"
