Here are the settings I have. I keep the AV button pressed and move the slider around and the F number does not change at all. It is always at F00

F00 indicates that the camera did not detect your lens. Either the lens is damaged or the electrical contacts of your lens (or camera) are dirty/corroded.

To check your lens, try this with another camera if you have another eos or if you can borrow one. If it also doesn't work with other cameras, then send it for replacement/repair.

Try also to clean the contacts of your lens and camera with a contact cleaner or by rubbing it with clean dry cloth. Do not use any corrosive solutions.

Hope that helps.
