AE expression help needed

[YoyoBoy]

Take a look at this video. The red line moves right as the time scale moves left (from 1945 to 1964). I'm wondering what expression I could give the time scale so that it moves automatically to the left when I move the red line to the right.

Basically all I'm looking to do is

When object Red Line x = 352
object Base x should = 2114

When object Red Line x = 1538
object Base x should = -658

<grumble> I really wish AE had a feature like 3DS Max's Reaction controller </grumble>.

Thank you.

Found the answer:
p = thisComp.layer("Red line").transform.position;
linear(p[0],314,1610,2222,-803);
