Continuity mistake: After Winifred, Sarah, and Mary get off the bus, when the young girl dressed as an angel stops and says, "Bless you," the candy bag she's holding switches from her left hand to her right arm, then back to her left hand, between shots. (00:48:10)
Continuity mistake: At the beginning of the movie, after the witches suck the life out of Emily, Winifred looks in a mirror and says, "Well...younger," and her green cape with a hood is on her in the closeup. In the next shot, when she says, "But, it's a start," she is not wearing her cape at all. (00:07:00)
Continuity mistake: When Max and Allison rescue Dani from the witches' house, they turn on the car lights to trick the witches into thinking it is daylight. After they get in the car and drive off, the same light that was supposed to have come from the headlight is still shining after they have left.
Continuity mistake: When the parents are at the party, Dani and Max's mother puts her hands up while she is dancing and you can see her wedding ring in the shots facing her, but in the shots facing Dani the ring is gone. (00:55:20)
Continuity mistake: When Winifred turns to stone in the graveyard, her fingernails rip shreds of cloth off of Max's sweatshirt (you can see them when he falls). Exactly one minute later, when he is lying down next to Dani and talking to her, it is clear that his sweatshirt is merely ripped, not shredded. (01:28:35)
Continuity mistake: In the scene just after Max summoned the "burning rain of death," when they're in the graveyard, Max's hair and jacket are completely dry after he was soaking wet only five minutes prior.
Continuity mistake: When the witches take Dani back to the museum, the rope they use to tie her up with changes from shot to shot. First it's up around her neck, then it's around her chest.
Continuity mistake: In the last scene in the graveyard, when Max is glowing and hanging off of Winifred's broomstick, his hands constantly go from a far to short distance away from the end of the broom between shots.
Continuity mistake: At the beginning of the film, Winifred's lipstick is small and in the middle of her upper and lower lip. However, as the scenes progress, her lipstick is bigger and she had no time to apply more lipstick - this is before the sisters are hung.
Continuity mistake: When the Sanderson sisters get on the bus, the headlights on the bus are on because it is dark out. They are visibly on at that point and as well as when the bus runs over Binx but, when the sisters get off of the bus, the lights are not on (it is still dark out and it is only a few minutes later). If the bus was merely letting them off (which it was, it drove away a few seconds later), why were the lights turned off? (00:48:06)
Continuity mistake: When Dani and Max wake up, the sun is out, and they say it's "5:00am," but when they go upstairs and Dani is caught, it's dark outside again.
Continuity mistake: In the grave yard, Binx is sitting on the book so Winnifred can't get it. A second later after their exchange, the cat is suddenly missing.
Continuity mistake: Near the beginning, right before the witches turn the boy into the cat, watch the girl in the chair. She's supposed to be dead because the witches sucked her life force out. She moves her knees. There are two mistakes in this scene. Not only is the dead girl moving her knees, the sheet covering them goes from being between her legs to completely straight.
Continuity mistake: As Alison holds off the Sanderson sisters with the box of salt, some shots show her holding the salt up close to the Sandersons while other shots the box of salt Is further away from them.
Continuity mistake: When the witches figure out that the "Burning Rain of Death" was actually water, it showed that they were all wet from before they managed to get under cover. In the next shot, as they leave the house, they're all bone dry.
Continuity mistake: When the sisters are in "Satan's" house and meet the wife, her curlers change position.
Answer: They were set up, beforehand, just in case. Winnifred knew about the spell, but she didn't memorize the incantation. So she needed the book to see how to cast it.

If you pause the movie, you will see that the book opened up to the Black Flame Candle spell.
