Not sure if this is what you’re asking, but two possible options come to mind. If you have 3 strokes with trim paths on them, and you want stroke A to animate its end from 0% to 100%. Strokes B and C you want to sit at 50% until stroke A has reached 50% then animate the end using the same value as stroke A. You can achieve this using clamp which will keep your value in a given range. Your expression on the end value of strokes B and C would look like this:

clamp(pickwhipedEndValueOfStrokeA, 50, 100);

The first argument is the value you want to clamp, the second is the lowest you’d like the value to go, and the third is the highest you want the value to go.

The other option, if you have 3 strokes with trim paths on them, and you want stroke A to animate its end from 0% to 100%. This time you want strokes B and C to animate on from 50%-100%, but you want them to be animating the entire time (You don’t want them to sit at 50% until stroke A gets there, you want them to be at 50% when stroke A is at 0% and then they all reach 100% at the same time.) You can achieve this using linear which will remap a value range. Your expression on the end value of strokes B and C would look like this:

linear(pickwhipedEndValueOfStrokeA, 0, 100, 50, 100);

The first arguments is the value you want to remap, the second is the one end of your input value, the third is the other end of your input value, the fourth is one end of your output value, the fifth is the other end of your output value.

Hope that helps!

That worked like a charm, thanks so much!
