Thank you both. I have tried logging in as a student and you're right the submission button is there.
I am interested to know why as an administrator, I cannot see the submit button on assignments that have been created in 2.2 and now upgraded to 2.4, but can when I create a new assignment in the upgraded version. I am using IE9 and this is site wide within college and so I can only work with this browser.
Many thanks, Chrissy
