I'm not totally sure about this, but I think that field is only applicable for fully hosted domains. Did you enter this for didgeridooconnection.com or vernsdidj.com?
BTW, I really do think that what you want to do is better served by mirroring rather than cloaking.
Also, I recommend getting rid of the www, but that's just my personal preference. My real recommendation would be either force it or get rid of it.
If you do want to solve your original problem in the original way, you might have to set up two cloaks, one for www.vernsdidj.com and one for vernsdidj.com. This is outside of my experience, though, as I've never set up a domain cloak. Hopefully, someone with real experience with domain cloaks will speak up here.
