Hi all

I seem to have inadvertantly done something in the custom functions to my autofocus. I wasn't watching what I was doing and went into custom function by mistake and and now my camera doesn't autofocus when I press the shutter half way. It focuses when I press the AF- ON button on the back of the camera. I have absolutely no clue what I have done and a couple of friends have also had a go at rectifying situation to no avail. Does anyone out there with a 7D have any suggestions?? I have been into the custom functions but I don't have any idea what they were set on to begin with so I don't know what's changed. Please help before I go completely mad... I've been trying to figure it out all day
