action="content.html"
The action= needs to reference a form handler program or script that will pick up the fields passed to it and do what ever you want. You can loose the target=
You also need a name= for the textarea
In this case, to display the fields with a line break after each using asp, you would replace action="content.html" with action="content.asp"
content.asp would be a file containing
<%
Response.write request.form("From")
Response.write "<BR>"
Response.write request.form("Name")
Response.write "<BR>"
Response.write request.form("Subject")
Response.write "<BR>"
Response.write request.form("NameForTextarea")
Response.write "<BR>"
%>
