addValueCallback to a 'slider value' on a NullObject.

I got it working when i was tidying things up for you!
Turned out i needed to add the index of the slider after the name of the slider in the path reference.

var sliderProperty = animationAPI.getKeyPath('dataInput,Effects,gebruikersTotaal,0');
animationAPI.addValueCallback(sliderProperty, function(currentValue) {
return monthlyNewUsers;
});

Thanks for your help and fast responses.

Hi, how are you creating the path to the effect property?
perhaps this can help as a reference:

check line 47 for example.

Your respond time is insanely fast! haha
I checked your reference and im on the right track.
the way i create my path is as follows:

var scaleProperty = animationAPI.getKeyPath('red_solid,Transform,Scale');
animationAPI.addValueCallback(scaleProperty, function(currentValue) {
return [100,monthlyNewUsers];
});

So this works because it's on the scale property. But in the following example i try to link to my slider control.
Where ''dataInput'' is the name of my AE layer, and "gebruikersTotaal" is the name of my slider.

var sliderValue = animationAPI.getKeyPath('dataInput,Effects,gebruikersTotaal');
animationAPI.addValueCallback(sliderValue, function(currentValue) {
return monthlyNewUsers;
});

This doesn't seem to work, but seems to be the same as in your reference on line 47.

do you have a link I can check?
if not, can you share the .aep?

great. Glad it works.
