Form Validation with Jquery not working

Form Validation with Jquery not working

Hello,
Ive made a form validation with jquery with the following code
  1.     $('#save').click(function(){
           
            $.ajax({
                url: "../scripts/availability.php",
                type: "POST",
                cache: false,
                data:{
                    stamp:           $("#stamp").val(),
                    jprefix:         $("#jprefix").val(),
                    tprefix:         $("#tprefix").val(),
                    starting_date:   $("#starting_date").val(),
                    ending_date:     $("#ending_date").val(),
                    starting:        $("#starting").val(),
                    ending:          $("#ending").val(),
                    colab_id:        $("#colab_id").val(),
                    id:              $("#id").val(),
                    session_id:      $("#session_id").val()
                },
                dataType: "html",
                success: function(msg){
                    if($(msg).html()==1){
                        if($("#starting").val() < $("#ending").val() && valDate()){
                            $("#serviceForm").submit();
                        }else{
                            alert ("Conflicto na data ou hora do serviço");
                        }
                    }else{
                        alert("Sobreposição de Colaborador");
                    }
                }
            });
        });






























  2. function valDate(){
            if($("#starting_date").length){
                if($("#starting_date").val() <= $("#ending_date").val()){
                    return true;
                }else{
                    return false;
                }
            }else{
                return true;
            }
        }










But the problem is that it some times works some times doesn't i couln't find any padron, and for as strange as it seems is works more times on IE than FF

I would apreciate your help :)
