I have this multipage userform, containing 16 listboxes in 16 pages.
page0 has no listbox.
Whenever an item is selected in one of these listboxes, some 30 lines of
code is needed to process that item.
The original code thus contained 16 x 30 lines of code.

It took me 2 years on and off to construct a loop to do the same stuff, in
about 40 lines of code.
It turns out that each list box is not a list box, it is a control.
Its position has nothing to do with page number, which in turn is
multipage.value

Amazing
