Replication acting strange

Hi all!

  I just finnish undating the design of a database. There is a main database on a server and each user has a local replica. All users have reader access exept for the administrators. The users are allowed to crate and modify one form in the database which is selected as a public access form. The users can create and modify the from correctly on there local replica but the new information is not sent up to the server for validation by the admins... The replica recieves ok, it just can't send info... What is going on!?! I have never seen this before, please help!

Thanks, Bryce.
