played around with this some more and here is where i ended up

x = thisComp.layer("Solid_1").position[0] + 22;
y = thisComp.layer("Solid_1").position.valueAtTime(time-0.03)[1];
[x,y]

seems to work ok. not sure it this is the best way to do this?

hello, new to expressions and i am trying to animate the position of a bunch of solid layers. i have my first solid and i set 2 keyframes for the position. i added an expression to my next solid layer and linked it to the position of my first solid and adding a transform of +300. this works fine but...
