Move an external camera with the same "input axis" of my character camera

Hi to everyone.
In my “first person view” project, my character is just a camera and a capsule component.
Everything works fine but when i want to change my point of view to another camera and i wanna use my INPUT AXIS
to move it…i can’t do that.
I don’t know why…i can use other button like “ASDW” but i wanna use my mouse to move this external camera
like i do with my character ( with is blocked with DISABLE INPUT in order to don’t let the character move around while you are controlling the other camera ).

the flow is around this

  • FIRST PERSON VIEW
    set view target with blend
  • CINEMATIC
    set view target with blend
  • NEW POINT OF VIEW ( which i can’t make it move with my mouse )

Some one can help me ?

thank you in advance
