Probably very easy, but I haven't gotten it to work yet. I have a comp has a null with an slider control and a text layer with the "thisComp.layer(1).name" expression on the source text.
I would like to update the selected layer (1), via the slider control, but it won't let me do this with just parenting.
Tips?

That is not possible via expressions. One workaround way to do it could be to have several layers and have the slider change the opacity of the layers to show and hide them.

Really? So I can't have a slider that changes the (1) value to (2) for example?

I think this maybe what you're asking for:
Code: Select all
slider = Math.floor(thisComp.layer("Null 1").effect("Slider Control")("Slider")); // ensure slider is an integer
slider = Math.max(1, Math.min(thisComp.numLayers, slider)); // ensure index is valid, clamped between 1 to numLayers
thisComp.layer(slider).name;
