I am after a script that will redirect the user to another page (open in new window) after adding certain dates.

for example,

I have a drop down list with check in and check out dates.
I put in check in date of 3/7/07 and check out 5/07/07 (and this may also be done in a calender pop up.) when I click search, it then takes me to a page which has those dated in the URL
eg. http://www.widgets.com/hotel07-07-03_07-07-05.htm...
