Watch your indents. Try replacing tabs with two spaces - that's the usual ruby standard way to indent. you can set sublime to do this automatically. To do so, open a .rb file in sublime. On the menu choose Preferences -> Settings - More -> Syntax Specific - User.

In the window that opens paste:
```
{
  "tab_size": 2,
  "translate_tabs_to_spaces": true
}
```
