What's wrong with this script?

[Strembitsky]

I recommend watching this:

http://wiki.frictionalgames.com/hpl2/tut...ng/article

It gives you basic idea of scripting . There are more tutorials in wiki!

I have! I also am currently following the tutorial on the wiki. Nothing is different in my code than the one on the wiki. Also, the error message always says that the code on the 13th line isn't right, so that means the function isn't written correctly. Could you please help?
