Custom Fields and slider images


Well, Ive search the place where I can add custom fields to my page EMPLOYEES, so, I edit it, I put the fields that i need, but these fields doesnt appear, the only one that appears is the '‘Position’'
I really need to change these fields :confused:

And I really need to know how to put more images in the header slider!!
