You had "selected" hard coded in the noon option for the time, that is why the select list wasn't working when a time before noon was selected. I removed it and re-uploaded the file.
Your field on the update page was named "Pickup_date" instead of "Pickup_Date"
I corrected those problems and your page appears to be working. Make sure to download the index, update, bookNow, and reserve pages since I also removed a lot of unnecessary code.
