Linking GoDaddy domain to Google Site

Hello,

I have a have a GoDaddy domain name and have also built a webpage on Google Sites. I have followed the instructions to link the two, however, when I type the website address: www.francerugbyworldcup.com I am taken to a GoDaddy page saying that GoDaddy has parked this site for Free and appears to be offering to sell me this domain name.

 

Any assistance would be much appreciated.
