Excel Macro to retrieve data from Zillow and cyberhomes,

I need to be able to run a macro in Windows 7 using the latest version of IE and Excel 2007 to send a large list of addresses out to zillow and cyberhomes and have the "zestime" and "estimate" returned to me in a separate column for each address. I have an excel spreadsheet that used to work for zillow but is no longer working on my new computer...I am willing to send that for guidance purposes.
