I found it! He actually included it in one of the project files I hadn’t looked into:
Thousands place-holder example:
slider = thisComp.layer(“Null 1”).effect(“Slider Control”)(“Slider”);
myDigit = Math.floor(slider/1000)%10;
previous = slider%1000/1000;
myVal = myDigit + linear(previous,.999,1.0,0,1);
y = linear(myVal,0,10,1500,0);
x = value[0];
[x,y]
In case that helps anyone down the road.
Thanks!
