In layman's terms, "parsing" is the process of a program (in this case 
POV-Ray) analyzing the source code, trying to figure out what you want 
the program to do; consequently, "parse error" means that there's some 
problem that causes the program to not understand the source code (or 
some part thereof).

I don't see any problems with the above code though - except that the 
ball is a very dark red and therefore barely visible. It renders with 
both POV-Ray 3.62 (which is the latest release declared officially 
stable) and POV-Ray 3.7RC3 (which is the latest release candidate for 
version 3.70).

BTW, which version are you using?

Could it be possible that you made a typo in the code you fed to 
POV-Ray, while posting excactly as shown on thinkquest.org?
