Before I get flamed for the obvious mistake, I will correct it.

number = ItemAddress(main_menu[0], number)->NextSelect;
if (number == NULL)
    number = MENUNULL;

This seemed to take care of the problem I experienced, but now I am asking 
myself how do you select multiple menu choices?  I tried a few things
such as SHIFT-RMB LMB, LMB...  In Browser one can multiple select files
with SHIFT-LMB, but is multiple selection supposed to be a feature of
menus?
