  Dear All

   

  I need your help.

  Please check below expression

  for (var k=0; k<21; k++);

  if(footage(“daily-by-location.json”).dataValue([1,k,8])==”618f344d1cb3e06d152fd4b3″){

  footage(“daily-by-location.json”).dataValue([1,k,4])}else{“No Match”}

  the json file located in harddrive.

  the result is false, but i know that “618f344d1cb3e06d152fd4b3” exist.

  the var k does not loop.

  if the var k is defined, for example “1” the expression would show the desired result.

  Is my expression correct or not?

  I haven’t tested this, but I think you’d want to structure it more like this:

  val = "No Match";
  for (var k=0; k<21; k++){
    if(footage("daily-by-location.json").dataValue([1,k,8])=="618f344d1cb3e06d152fd4b3″){
      val = footage("daily-by-location.json").dataValue([1,k,4]);
      break;
    }
  }
  val
