Direction without trailing slash is not working

EDIT: Disregard, had extra / in urls’ as show below.

The redirects of ^/pagetitle/[/]? and /pagetitle/[/]? will only redirect if the user goes to domain.com/pagetitle/ but not if the url is entered without a trailing slash ala domain.com/pagetitle.

What is the best syntax to insure that url’s with and without a trailing slash redirect? TIA!
