JavaScript is not sending drop down list selected info if valid

Hi
I create this JavaScript method to validate drop down box in asp.net form from sending information to DB but when all my entry is valid it will not send it to DB can any one help me to fix it

    $("input[id$=btn_createProject]").click(function (e) {
        e.preventDefault();
        var statusVal = $("#MainContent_ddl_status option:selected").val();
        var priorityVal = $("#MainContent_ddl_priority option:selected").val();
        var techVal = $("#MainContent_ddl_defaultTech option:selected").val();

        if (statusVal === "-1") {
            $('#msg_validate_status').removeClass("hidden ").addClass("Validator");
            e.preventDefault();
        }

        if (priorityVal === "-1") {
            $('#msg_validate_priority').removeClass("hidden ").addClass("Validator");
            e.preventDefault();
        }


        if (techVal === "-1") {
            $('#msg_validate_tech').removeClass("hidden ").addClass("Validator");
            e.preventDefault();
        }

    })

If I followed you correctly, I think you need to remove the first e.preventDefault(); which is at the beginning of your script.

oh thanks
