1) Script Title: Xin's Popup Calendar

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...pcalendar2.htm

3) Describe problem:
Hello! I'm successfully using multiple instances of this date picker in one form. However; I need to change the calendar's years to a drop down so the user can easily go back 20 years or more. I only want the calendars to display dates in the past. I also need to set a date on another instance of the calendar to a specific limit of 1940-1990. I can't see in the code where or how I may make any of these changes. Are any of these changes possible? If so, how?

Any assistance would be greatly appreciated!
