Maybe something like this:

s = thisComp.layer(“Control”).effect(“Slider Control”)(“Slider”);
pct = linear(s,70,100,0,100) + “%”;

It seems like the value of the slider doesn’t matter, just the index of the most recent keyframe. It will probably looks something like this:


s = comp("MainComp").layer("Value Control").effect("Value 1")("Slider");
v = value;
if (s.numKeys > 0){
n = s.nearestKey(time).index;
if (time < s.key(n).time) n--;
if (n > 0){
if (n ==1){
v = footage("Values.csv").dataValue([2,0]);
}else{
t = time - s.key(n).time;
v1 = footage("Values.csv").dataValue([2,n-2]);
v2 = footage("Values.csv").dataValue([2,n-1]);
v = linear(t,0,1,v1,v2);
}
}
}
v

The key to making something like this work is that your expression has to be able to figure out when the slider changed to a particular value. Do you have a keyframe for each slider value? If so, it’s fairly straighforward. If not, it’s more cumbersome, but it can still be done. So how are you driving the slider values, exactly?

This line:

leeway = 100 — percentageOfMaxWidth;

has an illegal character in it for the subtract operator. It should be:

leeway = 100 – percentageOfMaxWidth;

Something like this maybe:

timeA = 0;
timeB = 1;
val = Math.round(linear(time, timeA,timeB, 0, 3.9));
(val > 3 ? 3.9 : val)+’%’

If variable Line1 is false (corresponding checkbox unchecked), it skips the 1666.5 and moves to the else if part. If variable Line1 is true, it accepts 1666.5 as the result, and ignores the else if and else parts.

Yes, the value of a checkbox evaluates to true if checked, false if unchecked.

Try changing the last line to:

w = linear(t, 0, loopTime, wiggle1, wiggle2);
[w[0],w[0]]

You could combine them like this:

Line1 = effect(“Single Line Position”)(“Checkbox”).value;
Line2 = effect(“2 Line Position”)(“Checkbox”).value;

if(Line1)1666.5
else if(Line2)1582.5
else value

Note that Line 1 will have priority if both checkboxes are checked.

Where are you applying the expression? It needs to go on the Amount property of an Expression Selector.
