Ruby programming: Sub Array Indexing : I have an array, filled with multiple value types (Its the Ruby programming language so I can do that), one of which is a sub-array, which in turn contains 2 smaller sub-sub-arrays:

eg: `array = ['b','t','66',[[' ',' '],[' ',' ']],'h']`

When I run the program and request array index 3 (which should contain both sub-sub-arrays), the computer returns: `[[' '`, instead of the entire array index 3 which should be: 

`[[' ',' '],[' ',' ']]`

I am asking how this is occurring, and how I could extract index[3] in the above form.

 -Thanks in Advance.
