Javascript函数“不存在”.语法错误，但看不到它

javascript应该处理表单提交。但是，即使调用
script src="js/registerform.js"> 未捕获的引用错误：未定义 sendreg 。该函数称为 onclick。可以在尝试注册时在 www.r4ge.ro 上复制以及实时编辑。试过 jshint.com 但没有线索。

我将使用所需的任何剪裁进行编辑。

    function sendreg() {
          var nameie = $("#fname").val();
          var passwordie = $("#fpass").val();
          var emailie = $("#fmail").val();
          if (nameie == '' || passwordie == '' || emailie == '') {
             alert("Please fill all the forms before submitting!");
          } else {
             // Returns successful data submission message when the entered information is stored in database.
             $.post("http://r4ge.ro/php/register.php", {

                $('#form')[0].reset(); // To reset form fields
                setTimeout(fillhome, 1000);
             });

    }
    function sendpass() {

       } else {

    }
    function sendmail()
