Another Problem Again...

[Juby]

Not exactly sure if this is exactly how you typed this script, but you have so much wrong here...
+ Firstly, You can't just TYPE. You have to organize by "Entering" and hitting "Tab".
+ NOTHING can be put in front of a squiggly-bracket ("{ / }") - These guys).
+ You have to put .snt after SOUND files and .ogg after MUSIC files.
+ An area and a callback can't be the same name. It could possibly confuse the script.

+ You don't have to if you really wanted to, granted it would be difficult and confusing.
+ Yes you can, you can have the entire script file on one line, it makes no difference to the compiler as all compilers read script on one line. A function like "Testfunc(int para){ stuff }" would work.
+ Not all of the time, but recommended nontheless
+ Perhaps
