You can do this by remembering either the index or the name of the red slider (This is the solution that David suggested).

Hi Phil,

when you add a new slider, the variables pointing to other sliders get invalid and you should not use them anymore.
See in the scripting guide the section "Reference Invalidation" of the PropertyBase object.

You need to create a new variable pointing to the RED Slider after creating the other one. You can do this by remembering either the index or the name of the red slider (This is the solution that David suggested).

Best,
Mathias

I'm having a fun time figuring out a scripting problem and thought I =
would ask the advice of the script gurus on the list.

Basically I want to add 2 sliders then get the value of those sliders.

	var RED_Slider =3D selectedLayer.Effects.addProperty("Slider =
Control");
	var red =3D RED_Slider(1).value;

	var GREEN_Slider =3D selectedLayer.Effects.addProperty("Slider =
Control");
	var green =3D GREEN_Slider(1).value;

If I run the code above, it works great however if I change the order =
and assign the sliders first then try to get the value, AE gives me an =
"invalid object" error.

So the code below will not work.

	var RED_Slider =3D selectedLayer.Effects.addProperty("Slider =
Control");
	var GREEN_Slider =3D selectedLayer.Effects.addProperty("Slider =
Control");

	var red =3D RED_Slider(1).value;
	var green =3D GREEN_Slider(1).value;


It's almost as if when I add the Green Slider, it forgets the Red =
Slider.

Any ideas?

Cheers.

Phil
