I fixed it. You told me in another post that the dates needed to be formatted as yyyy/mm/dd and I figured out how to do it. I added the code:
dateFormat: "yy/mm/dd", to the datepicker and it worked. Funny thing is, if I add yyyy instead of yy, the year comes out twice in the field.
But I tested it and my email comes through properly. I hope it retains that format when I have it upload directly to the database.
