(in blank space, not one of the fields) and select 'form properties'. When the dialogue opens you'll see that you can specify what happens to the form results. You can choose to have them sent to you by email in addition to the FP default - which is to store the results in a special file on the server.
Take a good look through the options and ensure that you've specified your requirements correctly. When you've made your alterations, upload the changes to the server and then try the form ON THE SERVER - not on the copy you have on your hard drive. My reason for saying this is that you probably don't have the FrontPage extensions installed on your computer, and the form will not work without them.
