Do you mean you'd like to find the distance between the two zip codes? If so, I'd recommend you check out geocoder. http://geocoder.us/help/city_state_zip.shtml you can get the lat/lon for a zip, like this: http://geocoder.us/service/csv/geocode?zip=75034 so if you get it for both zips and then calculate it with the great circle equation, Robert's your father's brother. http://geocoder.us/blog/2006/04/21/calculating-distances/ ************** Ken Ferguson 214.636.6126 ************** ============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html ============================================================================== ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Introducing the Fusion Authority Quarterly Update. 80 pages of hard-hitting, up-to-date ColdFusion information by your peers, delivered to your door four times a year. http://www.fusionauthority.com/quarterly Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:247890 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
