  Array variable attached to slider not working right

  Posted by Stephen Schleicher on April 26, 2018 at 1:48 am

  So I’m trying to use a variable attached to a slider to control which line from a .json file the data is being read from.

  This works:
  eval(“var temp=”+footage(“miaa.json”).sourceText);
  X=0
  temp[X].R1

  This does not:
  eval(“var temp=”+footage(“miaa.json”).sourceText);
  X=thisComp.layer(“line”).effect(“Slider Control”)(“Slider”);
  temp[X].R1

  Can anyone help me out here?

  Try changing this line:

  X=thisComp.layer(“line”).effect(“Slider Control”)(“Slider”);

  to this:

  X=thisComp.layer(“line”).effect(“Slider Control”)(“Slider”).value;
