how to update resume on apple website

Last year I applied online to a local Apple Store, where I uploaded my then up to date resume. Since then, I have gotten a job at another place and now want to apply again at the Apple Store. However, when I go to my profile and see my old resume, I click edit but it just takes me back to the application and does not let my replace my old one with my most recent. I've tried uploading my new one, but it keeps saying I have exceeded the page limit. How do I replace my old resume with my new one?
