Well I was able to get it to delete one item at a time. However I must be doing something a little wrong since I can't get it to delete a selected item, or it crashes.

procedure Remove_Game(integer self, integer event, sequence parm) 
	for i = 1 to length(Game_List) do 
	end for 
end procedure 

getIndex() returns the index number(s) of the item(s) selected. Save that, and then deleteItem(Game_List,index) You can look at index to see if it is an integer or a sequence of integers.

procedure Remove_Game(integer self, integer event, sequence parm) 
object index = getIndex(Game_List) 
       ? index -- put this here for a peek at what is being returned 
       if atom(index) and index > 0 then -- an item was selected, so... 
       else -- multiple items were selected, so... 
         for i = 1 to length(index) do -- process each item 
         end for 
       end if 
end procedure 

getIndex ( list )  
Get the index of the selected item(s), or cursor position in an edit control. 
Returns: INTEGER: Index of selected item, or zero if no item is selected. 
Category: List Control 
For ListView and TreeView, this returns a sequence of all selected items. 
For MleEdit, EditText and RichEdit, this returns the cursor position. 
For List, this returns the index of the currently selected item.
