Capability parameter of add_submenu_page() function can only take a single capability, so if you are using the built in roles you can select a capability fro the long list that both administrators and editors have any of these (use any of these freely): moderate_comments manage_categories manage_links unfiltered_html edit_others_posts edit_pages edit_others_pages edit_published_pages publish_pages delete_pages delete_others_pages delete_published_pages … Read more
