What does FEE mean? The camera won't take a picture and I see that in the display of my Nikon N90S

FEE error message displayed on SLR camera LCD Description If the cameras LCD screen displays "FEE" in the area where the aperture is normally displayed, please ensure that the lens is attached to the camera correctly. This error message will appear if the lens is not attached correctly to the camera or if you are not using a CPU lens such as the Nikon AF or Nikkor P lenses. Alternatively, if the lens has an aperture ring, it may not be set to f22 (or the highest aperture number on the aperture ring - normally marked in orange). Select the aperture number marked in orange on the lens and lock it using the aperture locking switch to prevent this occurring again.
