Calling setInterval

I have a function that I need to call from within a movie clip timeline (the function script resides at _root). I would like to call it 2 times at 3 second intervals. The function call from this movie clip timeline looks like this:


_root.makeCircle(1010, 362, 6);

1010 = _x
362 = _y
6 = number of expanding circles to make

I can’t seem to get setInterval to work properly. Does anyone have an easy fix?
