Narrative:

I had received a clearance to FL310. I thought I dialed FL310 into altitude alerter. I was doing paperwork when ATC called and asked what altitude we were going to. PF (other pilot) said FL330, and I couldn't believe it, but FL330 was in the altitude alerter. I don't know if I mis-dialed FL330 versus FL310, or if PF put FL330 in.
