traffic light expression
I would like to apply traffic light concept to control opacity of some layers, i prefer to control it by typing a number in slider control.
eg. I have 8 layers
type 10, the opacity of layer 1 is 100 and other layers are 0,
type 20, the opacity of layer 2 is 100 and other layers are 0.
Can you help me please..
Thank you and have e great day,

I’m not sure where your slider will be, so you’ll have to add that, but the opacity expression would look like this:
s = (link to your slider control);
if (Math.round(s/10) == index) 100 else 0Dan
