Validating Calculation for Date Range

Hey guys I need the attached file to perform the following:

- When I type in the "Date Purchased" I need it to be validated by the range between "Date Start" and "Date End"; if it's out of range I need a message warning.

- When I type in the "Date Postmarked" I need it to be validated by before the "Postmark" date (under "Date End")

- *OPTIONAL* If either "Date Purchased" or "Date Postmarked" does not qualify I need "Q" to be entered as "No" automatically. And vice versa.

- I need it to print only the Qualifying addresses in the "PRINT" layout

if anybody can help me out with this. I really do appreciate it!
