Hello d0wnt0wn,
Yes. Right click the listbox & choose Format control and then the Control tab.
Enter the cell you want the selection to go to in the Cell link field.
Be aware though, that by using a Forms listbox (as opposed to the Controls Toolbox listbox) all you'll get in your linked cell is the index number of the selection. (ie, choose the third item, you'll get a 3 in the linked cell, not the text (or number) that you selected.)
Hope it helps.
