How do you reference a global array in a custom script window? Like "gv_variableName" is for regular variables, but what's arrays? I can't seem to figure it out. I'm sorry if there's an answer to this somewhere, but I can't seem to find it.
You can't dynamically assign / change an arrays length.
It either has to be a plain number or a constant. I don't think you can insert a constant in GUI though.. but in Galaxy (Custom Script) it works.
