Need A Bit Of Help With The Final Details

I am almost finished this project. :p There are just a few things left that I would like to do and I need some help.

1. Add an email notification when data on the form has been edited
2. Filter the form for only OPEN orders, status not equal to 6 or 7
3. When an order is closed (status field) I would like to default the "Date Closed" to today, but allow the user to edit the date if need be.
4. Once the status is closed and the date closed is entered, ask the user if they would like to create a followup order.

I have most of #4 done. I added code on the After Update event on the Status field to set the Date Closed to today and then disable the control, then ask if they would like to create the followup order. The users would like to be able to modify the date closed if they don't happen to do the entry until the next day. I have tried adding my code to the After Update of the date (which is updated with a pop up calendar), but once I select the date from the calendar, the focus stays on the date and the user is not prompted to create the followup order.

Any help you can offer would be wonderful

Thanks
Pat
