Trying to get laylines to display on proper respective sides of the gate

Having a great time here, Not quite working. There was an issue where the laylines are crossed and I think its tied to the fact that sometimes the two seperate points of the gate mark appear to have the same x y coordinate so the line function doesnt work? idk
