HTML Form Submit to table in same page

Couple of things with this. Your action attribute is empty. That’s the attribute that tells the browser where to send the posted form data. Should be a field or if you’re using AJAX, I always put # in there and let the javascript do it’s thing.

Not sure about the cf_name attribute in your input fields. I seem to remember that might be an implementation of Adobe ColdFusion but it’s certainly not HTML compliant.
