Ciao Xinod!!
guarda, ho provato sia così:

<script>
        mrg=0;
        function righrarrow () {
            if(mrg>-900){
                mrg=mrg-180;
                $("#secondB").css("margin-left",mrg);
            }
        }
        function leftrarrow () {
            if(mrg!=0){
                mrg=mrg+180;
                $("#secondB").css("margin-left",mrg);
            }
        }
        $("#secondB").animate({"margin-left":mrg},'slow');
    </script> 

...sia così...

<script>
        mrg=0;
        function righrarrow () {
            if(mrg>-900){
                mrg=mrg-180;
                $("#secondB").css("margin-left",mrg).animate({"margin-left":mrg},'slow');
            }
        }
        function leftrarrow () {
            if(mrg!=0){
                mrg=mrg+180;
                $("#secondB").css("margin-left",mrg).animate({"margin-left":mrg},'slow');
            }
        }
    </script>
