I have 2 listboxes (lb1 and lb2) and a menu. And 2 problems....
1) The menu selection controls what is displayed in lb1 based on selectedItem. lb2 displays criteria based upon what is selected in lb1. When the app loads, it displays the first menu item by default. How do I get lb1 to be empty until a menu item is selected?
2) listbox 2 (lb2) stays populated with the information from previous menu criteria until another item in lb1 is selected. I would like the contents in lb2 to clear when a new menu item is selected.
I am not sure how to accomplish these 2 tasks.
