Alright here's what I'm trying to accomplish. I want to be able to follow a given property(in this case position), but specifically the x or y position. I thought it would be as easy as setting a variable then adding the valueAtTime expression, but I'm definitely missing something.... I saw the delay expression but I'm still unsure how to apply that in this case.
x = thisComp.layer("White Solid 2").transform.position.valueAtTime(time - 1);
y = value;
