How to create a connection between to coordinate values ???

[BlackPyro1994]

Hi , I want to know how to make an Expression that can connect two values . I have an BlackLayer with an "Laser" Effect where I want to connect the Start Coordinate that everytime I change the value the Coordinate Value of my "Light" Effect copies this value automaticly.

Assuming your laser effect is on a 2D layer, it's probably going to be like this:

L = thisComp.layer("Light 1");
fromComp(L.toComp([0,0,0]))
