Continuity mistake: When Sam is at Carter's house to give him a lift to school, Carter (in his Snoop Dizzle look) is holding the script in his left hand and the bag's strap falls off his right shoulder when he sits down. Next shot, the script is in his right hand and the strap is back up on his shoulder.
Visible crew/equipment: Just before Sam and Carter show up at the pool for Carter's Zorro reveal, when Shelby, Caitlin and Madison are walking towards the camera as Caitlin says, "He was so mysterious, but really obvious...," the shadow of the crew's equipment moves forward with the trio, on the ground behind Caitlin. (Visible on fullscreen DVD.)

Continuity mistake: When Sam and Carter arrive at the pool, before Carter reveals himself to Shelby, the poolside gate and banner cast a shadow on the ground, to the right.

Continuity mistake: At school, when Austin is putting up the Cinderella fliers, he tapes the fourth flier on the bulletin board under the word "pep" and over the letters "Fri" in the word Friday. Next shot, the flier has moved to the left, and is taped beside both words "pep" and "Friday".
Continuity mistake: After young Sam has carried the box of her belongings up to her new bedroom in the attic, she lies down on her bed and as the camera pulls back the window shade is all the way up. It cuts to a wideshot as the camera still pulls back in the rain, and the shade is lower now.
Continuity mistake: After young Sam loses her father in the Northridge earthquake (noted in voiceover), she appears alone on the ball field, at home plate.

Visible crew/equipment: When David and Ryan force Austin to participate in the bachelorette 'Dating Game', the CD player sits on the bench beside Austin.

Continuity mistake: At the start, when Sam is reading the text message from Austin stating "Where have u been? We haven't talked...", on the cell display there are two bars in the battery icon in this close-up, but as she replies "We talked this morning", the battery icon is empty in the semi close-up. Then, when she reads his reply in the close-up, once again there are two bars in the icon.
Continuity mistake: At the dance Sam is wearing silver non-platform stilettos with silvery nail polish on her toenails. As soon as Fiona and the "Siamese" twins leave the diner, in the kitchen a much relieved Sam shifts her white gown and she is wearing white platforms and her toenail polish is quite gone now.
Continuity mistake: When Austin is forced to sit on the bench to meet the bachelorettes, the large words "friendship circle" are above the bench. In the wideshots Austin sits in front of the "ship" part of the words and Ryan is in front of "circle", but in the close-ups Austin's in front of "friend" and Ryan's in front of "ship", about 2 ft to their right (viewer's left).
Visible crew/equipment: When Austin is putting up the Cinderella fliers at school, just as he tells David and Ryan, "The phone's locked.
