<input type="hidden" name="formname" value="template-name">
................ (your form)

TIPS:
To obtain a perfect transition between your form and the Form created by nsForm, use the preview button or the html to see if the html is similar. If you are not html programer, maybe the better alternative is to create the form using nsForm and then using the html exporter utility, you could copy and paste to your web editor.
