I assume in your real code, that ends with `]`, not with `)` as above?
As above, it's a syntax error.

Do your button instances have a function called `_opacity` (with the
underscore)? I'm not a scripty-head and maybe I shouldn't be posting,
but the effect is called Effect.Opacity, and usually when scripty
mixes effects in as element methods, it's the name of the effect with
an initial lower case letter, so wouldn't that just be `opacity`?
FWIW,
