Thanks for your reply. The unassigned variable was just an error ai made when posting to the group. Thanks for the tip on using the $A. I can now get the funciton to work under some conditions, e.g., on a mousedown event. The problem is that it won't work on a window load. in the code below, clicking the "CLICK ME" link corretly return '2' as the count. But the onload event always reports '0'.
