Audiosource list empty?

Hello, i am making a pretty basic text adventure game following a tutorial that i finished a w$$anonymous$$le ago and i started adding new systems. I'm very new to unity, so please excuse any poorly written code. In my state object(code attached in the pastebin links below), i have a variable called optionsounds, w$$anonymous$$ch is a list in the editor that takes sounds and plays them when certain options are pressed with the number keys. In my main script(at the bottom) I try and acess it and play it, however using debug.Log i found that the list is completely empty w$$anonymous$$le in the editor I have set the list to have a sound in the first option. When i put the sound in, it throws me a "t$$anonymous$$s t$$anonymous$$ng is null error", w$$anonymous$$le my code explicitly checks that its not null before trying to play it, however if I just dont put anyt$$anonymous$$ng in the list, it works fine.
Basically my main problem is that the list in state is empty when accessed in my main script.
