    I can't understand why the code doesn't seems to function very well

    can you help me please because I can't understand why the code doesn't seems
    to function very well:

    in onkeypress it must verify if insert number or string value in the fiels,
    but it doesn't seems to function very well
    (in frontpage it works but here it doesn't)

    PROGRAMMA IN FRONTPAGE

    <form method="get" name="f">
    numerico<input type="text" name="t1" onkeypress="ret urn
    numeralsOnly(ev ent)"/><br/>

    stringa <input type="text" name="t2" onkeypress="ret urn
    lettersOnly(eve nt)"/><br/>



    PROGRAMMA IN PHP


    <!doctype html public "-//W3C//DTD HTML 4.0 //EN">

    var charCode = (evt.charCode) ? evt.charCode : ((evt.keyCode) ?
    evt.keyCode : ((evt.which) ? evt.which : 0));
    if (charCode > 31 && (charCode < 48 || charCode > 57))
    {
    alert("Puoi inserire solo numeri!");
    return false;
    }
    return true;
    }

    function lettersOnly(evt )
    {
    evt = (evt) ? evt : event;
    var charCode = (evt.charCode) ? evt.charCode : ((evt.keyCode) ?
    evt.keyCode : ((evt.which) ? evt.which : 0));
    if (charCode > 31 && (charCode < 65 || charCode > 90) && (charCode < 97 ||
    charCode > 122))

      Suggest you put it through a PHP debugger. There are many free and
      paid debuggers. I used zend (paid, but very nice).

          You seem to be confusing Javascript and PHP -
          Javascript is *client*-side while PHP is *server*-side.

          Assuming that PROGRAMMA IN FRONTPAGE and PROGRAMMA IN PHP are seperate
          files, your PHP program will not be aware of any data until the form is
          submitted to the server, therefore your validation needs to be done in
          the browser.

          Regards,

          Andy
