Your question could be seen to require clarification because the example you posted will just manually print a header (since you use CGI you can use it to print the header for you) and display an text input with a predefined value. You have no <form> element, and no way of submitting the input to your script. You seem to be missing the very basics of how all this hangs together. https://developer.mozilla.org/en-US/docs/Web as well as the CGI documentation (note the clear warnings at the start), Tutorials -> Web Programming I know what I mean. Why don't you?.
