can someone help me with the changing of the codes? instead of setting the intervals, i want to change it into something like adding a textbox for users to enter the intervals. and i also want to try to change the codes so that only when the user click, then the arrow would move.  
so its two separate favors… 1.adding textbox… 2.using onMouseDown function to move the arrow.
