Why doesn't http://pastebin.com/raw.php?i=yPNasgKn compile?

A compiled version of the script is in the Dawnguard.bsa. I even decompiled the compiled script to see if the source and the compiled version differed but they do not.

How do you compile this script?

the problem is definitely this line

Sound Property SoundDescriptor  Auto  

you just can't name that thing SoundDescriptor from what the errors say.

name it Curt instead, should compile then.

edit: just tried it, compiles like a charm with that changed
