Na początek przyda się
[XML] pobierz, plaintext 
  1. <form name="new_product" method="POST" action="--WEBBOT-SELF--" enctype="multipart/form-data">
[XML] pobierz, plaintext
żeby JS mógł w ogóle odnaleźć formularz.

  6. }else{
  7. document.getElementById('netto').value = '';
  8. document.getElementById('brutto').value = '';
  9. alert('To nie jest liczba !')
