If I understand your answer correctly,
ListBox2.Value = ""
ListBox3.Value = ""
would set the current values to nothing.
What I want to do is to "turn off" the highlighting (that may be an incorrect term to use). When you select an item in a listbox, the "active" selection becomes an inverse highlighting, showing the item that you clicked on. I use thre listboxes for employee information(one for onshift, one for out of office, and one for employees temporarily "farmed out").
When I initially click on "GEORGE", an "onshift" employee, the active selection (GEORGE) becomes highlighted.
Then when I click on "TOM", an "out of office" employee, that active selection (TOM) is highlighted IN ADDITION, "GEORGE" from "onshift" listbox is still highlighted.
What I want to do, Is when I make the second selection (clicking on "TOM"), I want "GEORGE"s highlighting to turn off.
