Gandi.net Groups

hi
I have registred a new domain with gandi and I'd like to transfer an old
domain (at godaddy) to gandi too.

The process confuses me a bit, because in about the third step you see
sth like:

-----------https://www.gandi.net/domain/transfer/iden...

Owner and contacts for your domains
For all domains in your shopping cart

Admin contact <MY GANDI HANDLE>       Create       Search

Technical Contact <MY GANDI HANDLE>       Create       Search

Billing contact <MY GANDI HANDLE>       Create       Search

[SUBMIT]
-------------------------------------------------------------------------------------------


now when I click on submit, it throws an error message :

" Errors:
* The 'Phone number' field is mandatory"

Why this message?
My contact information is complete, incl. my phone number.

Regards
