IT form validations bugs

$(".itform .send").click(function(){
        var form = $(this).parents(".itform");
        var email = form.find('input[name="email"]').val();
        var name = form.find('input[name="name"]').val().trim();
        var phone = form.find('input[name="phone"]').val().trim();
        var regEmail = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
        var regPhone = /^((\+38)[\-]?)?(\(?\d{3}\)?[\- ]?)?[\d\- ]{7,10}$/
        var emailError = form.find('#errorMess');
        var nameError = form.find('#errorName');
        var phoneError = form.find('#errorPhone');
        var namephoneError = form.find("#errorNamePhone");

        if (name == '' && phone == '' ) {
            namephoneError.css({display:"block"});
            namephoneError.css({opacity:"1"});
            namephoneError.animate({opacity:'0'},2000);
            return false;
        }
        if (name == '') {
            nameError.css({display:"block"});
            nameError.css({opacity:"1"});
            nameError.animate({opacity:'0'},2000);
            return false;
        }
        if (phone == '') {
            phoneError.css({display:"block"});
            phoneError.css({opacity:"1"});
            phoneError.animate({opacity:'0'},2000);
            return false;
        }
        if (!regEmail.test(email)) {
            emailError.css({display:"block"});
            emailError.css({opacity:"1"});
            emailError.animate({opacity:'0'},2000);
            return false;
        }
        if (!regPhone.test(email)) {
            phoneError.css({display:"block"});
            phoneError.css({opacity:"1"});
            phoneError.animate({opacity:'0'},2000);
            return false;
        }
        else {
            emailError.hide();
            $.post("./mailIT.php", $(this).parents(".itform").serialize(),  function(data) {
                _gaq.push(['_trackEvent', "Client Feedback IT School", "Email", "Email"]);
            });
            form.find('.success').css({display:"block"});
            form.find('.success').css({opacity:"1"});
            form.find('.success').animate({opacity:'0'},2000);
        }
    });

If you follow code of validation logic you will see that reg expression evaluates wrong instance.

The main problem is here.
