Hi, I am needing a search area for my website that allows people to put in their zip code and put in the amount of miles within that zip code. Just like AutoTrader.com If you would like to view what I'm talking about then you can go here... http://www.autotrader.com/fyc/index.jsp?bkms= I just can't figure this one out. I appreciate any help given. Thanks.

What have you done to try to figure it out? Hard to give a specific answer without a specific question.

Without digging too deep into the code on the site I see a for that's likely storing zipcodes in a database somewhere. Since the page is index.jsp it stands to reason that jsp is the language being used to interact with the database. I saw a bunch of links to javascript files in the source code as well.

What's going on is someone enters their zipcode and how many miles they want to look within and those are used to search the database. Somewhere there will be a distance calculation to know which zipcodes are within X miles of the zipcode entered.

Use Google Maps, read it's API.
