Please select a date from the calendar that will pop-up when you click in the box.
Using a Datepicker ensures that only valid dates are selected. We have commented-out a line of code for the Datepicker control that allows the user to select weekdays only. You can experiment with the date format to customise the text that the Datepicker puts into the input box. jQuery offers a wide range of themes for those of you that are really keen to impress.
