Need help with Jquery calendar

I need help with a calendar that is done with Jquery. When you load the page, I have default dates in there for testing. These will be dynamically driven and all the coding is done for that. 1. If you click on the date box, the calendar will load and you can see that the dates adjust in the datebox and the calendar on bottom just fine. 2. You can slide the calendar handle and it will adjust just fine as well as populate the date boxes just fine. 3. This is where the problem is. After you adjust the sliding calendar and it populates the date box, when you go back to the date box and select the drop down calendar, it will then not adjust the bottom calendar accordingly. If I do a refresh it will go back and the drop down calendar will populate the bottom calendar accordingly. However, I do not want a refresh. I am unsure of how to code this to make it work correctly. I have included all files and I am sure it will take someone a few minutes to pinpoint what to do. Please mark all coding so that I know what you have done.
