Error: Name not defined within scope Grrrr

[Existential Conundrum]

I have a couple sounds I'd like randomize play. On state entry is fine. it's just to enhance thunder and rain that is audio silent. I found this:

http://wiki.secondlife.com/wiki/Script:Random_Sounds

But, I keep getting an error even if I type the names of the sounds:

soundnames = [Thunder-03-01, Rain-Thunder-01, Rain-Thunder-02, Rain-Thunder-03];

not sure if my syntax is wrong or I'm typing the wrong thing or what. Blank gets same error. I have no idea if there is a better way. Please and thank you for help.

You forgot the quotes. Those are string constants.

Thank you for replying. It's still giving me the same error. What am I doing wrong?

list soundnames;  needs to be declared as a global variable. As its referenced in both the LoadSounds() function and in the timer event
