list view
List objects (combo boxes, list boxes and option buttons) display the
		contents of lists. As each object is placed in an Application Studio report
		it is named, by default, 
Listview[n], where n is a sequential number. Various properties of list objects can
		be returned with formulas. For example, =ListView[n].ElementCount returns the number of elements in the list. You can
		change the default name and use it in the formulas.
