    Expression help. Opacity using a null slider



      I'm using the expression below on a few layers in order to achieve a 'rolodex' look. The expression was applied to the x axis of the layers.


      numCards=thisComp.layer("Null 1").effect("numCards")("Slider");

      viewCard=thisComp.layer("Null 1").effect("viewCard")("Slider");


      v=((index-1) * (360/numCards) + viewCard*(360/numCards))%360;


      if (v<10) {


      } else {



      I would like to make it so that I can control the opacity of the given layer so that lets say when the 'card' (layer) in question is at a certain point in its cylce the opacity will go from 0 to 100 and then fade back down to zero.
      This expression was taken from somewhere else, and I'm learning them (but slowly).
      Thanks a lot for your help!
