Trying to Redirect Website

I was trying to redirect one of my WordPress website domains to another.

I originally purchased http://www.barbarabee.com and then I purchased
http://www.bumpsarebad.com.

I would like to have both sites work, but direct to the
http://www.bumpsarebad.com location.

In trying to do that I made an error and received this message, on Saturday
5/11/2013 at 8:48am. Please assist. Thanks! Barbara Bee
