Continuity: At the end of the movie, when Jill is in the hospital and the balloon pops, there are only two balloons: the one that popped and a mylar balloon.

Continuity: When Jill puts the piece of paper with the code for the security system on top of the system in another scene it's gone, and when she returns it's back again.
