Grid in camera view?

Hi
I’m brand new to Toon Boom and am slowly working my way through the tutorials. Currently I’m on Chapter 35 “Importing a Model” I’m suppose to turn on the grid in the camera view, but it won’t go on. It shows that it is highlighted, but no grid shows up. I can see it in the drawing view. Can anyone tell me what I’m doing wrong?
Thanks,
Ellen

Never mind. I figured it out. I was in the transform tool, but when I checked the selection tool the grid showed up.
