Urgent advice needed for family visitor visa to uk

Dear all
I would appreciate any advice regarding sponsoring a relative. I have sent bank statements ending upto 7th aug 2011(6months). I have not yet received the most recent statement(8th aug to 7 th sep). I have been to thd local hsbc branch who gave me a duplicate statement and put a stamp of their sort code on it and signed it. The statement was printed on a white paper and does not have the bank logo on it. The statement does not have my address on it.
Would this statement be considered as a valid document?

No address, but it must at least have your name? If the bank have certified the statements (and you appear to indicate they have) they should be fine.

Thanks for the reply.
