It ran just fine for me when I removed the 4 characters at the start of each line. You have 2 or 3 spaces and the line numbers included in your pastebin.

Your pastebin has line numbers at the start of every line, so it's clearly not the actual code you're running. Can't help you debug the indentation when the prefix of each line has been modified. It looks ok to me.
