  Posted by Suniel Surya on June 16, 2015 at 8:14 am

  ok.. I’m Creating a Template For Our local Tv…It’s just like on Lower Third… but actually it’s local ad

  we are using 3 positions (left,Right,Bottom) and we never used 3 positions at a time…

  for that… i created 3 solids and name as left,right,bottom
  then i created a adjustment layer and applied layer control expression… and check box expression control

  how can i link my solids to expressions…

  actually what i need is if i select bottom in layer control that solid (bottom) will show

  and if i select right in expression control then right solid will show and other two layers will hide…

  and some i don’t need 3 solids expect the logo layer.. for that situations i applied checkbox control .. if i check on checkbox control one of the three layers will show ( Based on my layer Control Expression).. if i un check all 3 layers will disable

  please check below images for more details :-

  

  

  

  i'm using this code for checkbox control expression for on/off the layer :-

  if(thisComp.layer("Controls").effect("Layer On/ Off")("Checkbox") ==0) 0 else 100;

  but this expression on /off the all layers... but i need if i check on checkbox control and then i select which layer will show from layer control expression
