Dave, You can't inter-mingle server-side code (CF) and client-side code (JS.) CF runs strictly on the server, while the JS in this example runs strictly on the client-side.
You can use techniques like covered in my article "Client-to-Server Communication Using DHTML"--which is at: http://www.pengoworks.com/index.cfm?action=articles:gatewayApi To simplify the work, I've written a Gateway JavaScript API (JSAPI) which can be downloaded at: http://www.pengoworks.com/workshop/js/gateway/ Conveniently enough, I even have included examples to do what you're trying to do: http://www.pengoworks.com/workshop/js/gateway/zipcode.htm Hope this helps! -Dan > -----Original Message----- > From: Bosky, Dave [mailto:[EMAIL PROTECTED] > Sent: Monday, March 24, 2003 10:00 AM > To: CF-Talk > Subject: Accessing JS variables in CF? > > I have a form field called Zip and want to lookup/populate the city/state > fields > based on the zipcode entered.
