I have looked at your email files and I can confirm that there is nothing specified in the body for the message. You should edit the UE server behavior on the page and specify to edit the page in DW. This will allow you to craft the body of your message to ge whatever you would like it to be. To get the data from your form on the page go to Bindings > Form Data and select the form page. You can then drag and drop the values directly onto your page where you would like to see them.
To andrea, have you read and followed along with the read_me.htm for the contact form sp? What step are you having trouble with? Really it should be a matter of updating a couple files and uploading them to your server to get them to work. Please post back with any questions that you have in a new thread to avoid any confusion in the current thread.
