Well, I didn't see any Back buttons on that site, but...
Whatever parameter[s] you pass to your query, you have to pass to=20
whatever link you click, then pass back to the query page through=20
your back button or link. So, if you have 3 hidden input fields:
location
cuisine
restaurant_name
When your list of restaurants come up, and you have a link to each=20
one, pass the parameters as a query string:
href=3Drestaurant.cfm?id=3D#id#&location=3D#location#&cuisine=3D#cuisine#&re=
st=20
aurant_name=3D#restaurant_name#
That may have wrapped, but you get the idea.
Then you can have a back button with hidden input fields, or a text link bac=
k.
href=3Dqueryresults.cfm?location=3D#location#&cuisine=3D#cuisine#&restaurant=
=20
_name=3D#restaurant_name#
Notice you won't need to pass the restaurant ID back, just the=20
parameter[s] that the query needs.
Keep in mind that items such as the restaurant name that people type=20
in that may have spaces, etc. you will need to URL Encode when you=20
place them into a query string:
restaurant_name=3D#URLEncodedFormat(restaurant_name)#
