Itunes and Google contacts

Dear All,

First of all but my English is not perfect.

I have a problem with the sync of my contact stored in Google Contacts and Itunes. When I am on the "infos" section in Itunes and I choose to sync my contact with Google contact, a window appears. I write the login and the password of my Google account and i click on "ok"...It seems to search but the windows to log to Google contacts appears again. So, I re-write my password, and click on Ok, it seems to search, etc, etc ...

I checked several times after sync in my Iphone and I have no contact.


Does anyone has a solution to resolve this login problem ?

Thanks a lot.

JM
