$post 404 NOT FOUND why?

Hello all

I have this problem where just I can't find why is not working

the following code makes me mad


In the first .external I got 404 NOT found file1.php
the second where is exactly the same working and finds file2.php
  1. // This not working
  2. $('.external').bind('click', function () {
        var value = $(this).attr('href');
        $(this).attr('target', '_blank');
        $('#number').val(value);
        $.post('file1.php', $('#numbers').serialize(), function (data) {
            $('.rea').html(data);
        });
    });
  3. // this working
    $('.outer').bind('click', function () {
        var value = $(this).attr('href');
        $(this).attr('target', '_blank');
        $('#link').val(value);
        $.post('file2.php', $('#links').serialize(), function (data) {
            $('.rea').html(data);
        });
    });

NOTE: html forms is same, and yes file1.php exist

Please any idea???
