7d aperture dial not working

I just bought a store display 7d.Idk if this is a bug or Im missing something.I went through all the menu.I set the dials correcting in custom settings.the only time the round dial works with aperture is when I go in quick control and put it on f-stop and I spin it.I tried switching the dials and made the round dial into shutter speed and it still didn't work.I really like the camera.Can someone please help.Should I return it?

Do you have the Lock switch set in the "off" position, lined up with the white line on the back?

the lock is turned off

o wow the lock has to be lined up to be turned off? now its working.Thank you.I really appreciate it

Theres only 2 positions. on and off. on is lined up unless your lock is faulty.

Easy mistake with these guys; glad it was that simple

I had the same issue when I toyed with the 7D. It freaked me out.

When I first got mine I had to scratch my head and re-read the manual several times.

In fact, I had it out re-reading some items yesterday.

The 7D is very far from a P & S, but it is a sweet machine.

For the first few months after I got mine, when it didn't work "right", I always assumed it was me and not the camera. Spent a fair bit of time searching for settings and answers. It likely helped me understand it better in the long run. Frustrating at times though

I was scared that mine was broken when I first got it too. I couldnt change mine from auto all focus points. I thought it was broken... then, I couldnt get 8fps. I was getting about 3fps, and then I realized it slows down in low light.

I freaked out too.I really like the camera though

mine is lined up and its working.I guess it is faulty but it doesn't really matter for me unless it gives more issues
