Hello all,

I’ve been trying to rejig the expressions in this post to work for my needs to no avail. Maybe I’m barking up the wrong tree? My javascript knowledge is minimal.

I’m trying to accumulate the width of multiple layers if they meet a condition.

In basic english:

Look through all layers with an index < current layer. If the opacity == 100, get width of current layer and add to a total.

Thanks in advance!
