Question regarding routing

I have a signup page in the directory /users> i.e. /users/register.php

I wish to redirect on success to myprofile.php so I have a route defined as:

Giving this in the .htaccess file

I use a browser goto() in server action success event pointing to “myprofile”

But the page, on success, redirects to

/users/myprofile giving a 404 error

Not, as i would expect

/myprofile which works correctly

Must be missing something obvious, never had this issue before

Anyone help?
