It appears that you pulled your .csv file into the timeline, so you should be able to use a Source Text expression like this:

n = thisComp.layer("MCBU Roster for Video copy.csv")("Data")("Number of Rows");
idx = Math.min(timeToFrames(time),n-1);
footage("MCBU Roster for Video copy.csv").dataValue([0,idx])

What does the .csv file look like?

[Dan Ebberts]

Presumably, that would have to be done with an expression, but unfortunately, there’s currently no way for an expression to apply multiple font styling to a single text layer.

[Dan Ebberts]

That’s surprising because I’m running your code and it works for me:

function getActiveComp(){
	var theComp = app.project.activeItem;
	if (theComp == undefined){
		var errorMsg = localize("$$$/AE/Script/CreatePathNulls/ErrorNoComp=Error: Please select a composition.");
		alert(errorMsg);
		return null
	}
	return theComp
}
function createShape(targetComp) {
	return targetComp.layers.addShape();
	}
function createShapeGroup(shape) {
	return shape.property("Contents").addProperty("ADBE Vector Group");
	}
function createPath(group) {
	return group.property("Contents").addProperty("ADBE Vector Shape - Group");
}
var comp = getActiveComp();
var shp = createShape(comp);
shp.name = ("Curve");
var curvgrp = createShapeGroup(shp);
curvgrp.name = ("CurveGrp");
var curv = createPath(curvgrp);
curv.property("Path").expression = "value";

[Dan Ebberts]

Try this one:

curv.property("Path").expression = "value";

Ah, OK. I think in your addCheckbox() function you need to change this:

chz.setValue(defaultValue);

to this:

chz("ADBE Checkbox Control-0001").setValue(defaultValue);

[Dan Ebberts]

It works for me if I comment out the addSlider() calls since that function isn’t included. If I don’t comment those out, it errors out, and it only creates one null.

[Dan Ebberts]

Try changing this line

rayon = (thisComp.layer("TraceArc").content("Ellipse Path 1").size) / 2;

to this:

rayon = (thisComp.layer("TraceArc").content("Ellipse Path 1").size)[0] / 2;

[Dan Ebberts]

This should tell you how many levels of parents a layer has:

L = thisLayer;
n = 0;
while(L.hasParent){
  n++;
  L = L.parent;
}
n

Maybe something like this:

t2 = key(2).time;
t3 = key(3).time;
t4 = key(4).time;
t = time;
if (time >= t3 && time < t4){
  t = t2 + (time - t3)%(t3 - t2);
}
valueAtTime(t);
