Camera doesn't read the aperture on the lens. What is happening?

[GuiMenGre]

I'm using a Nikkor AF 70-300mm 1:4-5.6 G. The aperture displayed on the camera body (viewfinder, front screen and top display), doesn't change when I manually change the aperture ring on the lens. It displays the aperture set on the front dial. The lens won't adjust to the aperture set on the front dial, neither when pressing the shutter realese nor the PV button. This is when shooting manual, the autofocus works properly on shutter priority, program and auto modes.

I'm confused about this question because I don't think any G series lenses have aperture rings. If this is a D lens, instead, you will need to set the aperture ring to the maximum aperture, then control of the aperture can only be done through the D7200 aperture control dial. With a G series lens, the only way to change the aperture is also with the camera's aperture control dial.

What I thought was the aperture ring is actually the focus ring. I see now the aperture is working properly. Begginer mistake
