Connecting two moving layers with a line

Hi,
I have a comp with several small, red dots that move independently. I want to add lines connecting some of these dots so that when the dots move towards/away from one another, the lines reposition themselves to stay ‘stuck’ to the dots.
If I can get this to work, some of the dots will have more than one connection. Perhaps this is important to note, I wouldn’t know being an expression fool.
Any ideas would be greatly appreciated!

You can use a Generate > Beam effect on a full-screen solid to draw a line between two points, all that remains is finding out the starting and ending point of the line:
Starting Point:
l = thisComp.layer("beginDot");
l.toComp(l.anchorPoint);
Ending Point:
l = thisComp.layer("endDot");
l.toComp(l.anchorPoint);

Use the beam effect on a comp sized layer and pickwhip the Starting and Ending Points to the position of your dots.

Tried this with the position value of a text layer so far, didnt work.
In what way? Do your text layers have parents?
