The form is very basic except that the select box only has one element. The reason is that more would be silly. We're done here. The script code is a little lengthy but stay with me here. You'll note it's just the same thing again and again.
Most scripts are like that.
Copy and paste the script from the new window into your HTML document. That's a Netscape thing. Notice the script is in two sections. It follows the path document, then the form name, then the form element name. If we didn't have this, the new text would simply be written under the existing text.
