Aye simple enough...
It's Lua script, not java or python or whatever. Semi-colons; are not the same as end. The only reason I use them (rarely) is for defining split sections when I code multiple things on the same line...
print(x + y); print(a + b); if x + y == a + b then print("true") end
Here... (obviously I can't test if it's working or not).

... You should use smaller variable names & less whitespace - nesting is also a good idea, as it makes it easier to determine what is what. Also I don't recommend having ? marks in the object names. & final note: you don't need to add the volume stuff as it automatically gets written to the config.ini each time it's updated - don't ask me why as I don't know.
Quick tip: write your scripts inside of a text editor like sublime text or atom. As it makes life much easier. Both of them have multi-line editing. Multi-line / word search & replace. Auto-completion, theme & color syntax. I recommend sublime text though as it's still better than atom (at the minute) as it remembers all tabs & their content when you close the app regardless of whether or not you saved.

, script is working now. Yeah I do use Sublime text, but I had no idea of the finer features (multiline editing) before this!
