How to view python error messages? I'm following a tutorial and I can´t go forward and finish the tutorial. My problem is that when i click on run script it gives me a problem saying "Python script fail, look in the console for now..." 

I use the recent blender and blender 2.69 and both of them give an error.

 

The problem is in the top red line. The tutorial I'm following is https://www.youtube.com/watch?v=jipaKhQWDeg Can't pass from the 15:00 minute.
On Windows you can toggle the console windows using the Menu: Window / Toggle System Console
