Line drawn from 1 mc to another using mouse

I’m pretty green to Flash CS3/AS3, so maybe this isn’t so difficult to accomplish? for someone with better knowledge?

I’m working on a project that needs to do the following:

Custom cursor (got that down)

5 movieclips on stage, that when clicked, bring a response(another movieclip pops up with text).

A line drawn from each movieclip after they have been clicked - to the next one that is clicked (in no particular order). (following the mouse, sort of) but not drag and draw.

So, the line starts from the center of the screen (the 1st position of the custom cursor)
then as each movieclip is clicked, that (movieclip) would be the new starting point for the line. - pretty much creating a web of lines from each point to the other.

any ideas?

its got to be something with the lineTo, moveTo, but I can’t get it to use the x + y coordinates as the next “start” point of the line.

Any ideas/help would be great-I have to figure this out!
