Narrative:
We were cleared to FL330, and FL336 had inadvertently been set in the altitude alert device. We had a block V autoplt with automatic leveloff feature and I monitored it as we approached FL330, but had my attention diverted as we passed FL330. At FL333 I realized we were above FL330 and made an immediate correction to descend. We topped out at FL334 and descended to FL330.
