If he has submitted the form, he cannot edit and resubmit the form for two weeks.
If it is for a New Title, he will have to wait for the title to appear and then add the rest of the credits -- or for the title to be rejected - which should release the form.
If it is just an add/update to a current title, he can just start a new submission adding the rest of the data in that one. (The history data can be used to verify what has already been submitted.)
