Error on &m_Width and &m_Height

So im messing around with GLFW and I am trying to create a window with a viewport to make sure that stuff is centered around the screen, i seem to come with this issue but i'm not entirely sure what is wrong as I believe I have covered what should be covered.

You have forgot the parentheses after the function names.
Oh so I did, thank you man!
