Returning the index and changing the background of item clicked.

Returning the index and changing the background of item clicked.

Hi I want to be able to change the background of the .full_wifth class if it also has the class .bbc from red to black.

I have included a fiddle:   http://jsfiddle.net/a4poster/YmG8A/58/

I also want to return the index of the full_width class that has been clicked.

Many thanks,
Paul.
