一个简单的js计算取值问题

帮我看看这个段代码哪里错了，合计金额 那个位置总是计算取值不对

  $(function() {
    var a = $("#cartBody");
    var c = $("#divNone");
    var b = function() {

            $.PageDialog.fail(t, s, r, q)
        };
        var n = function(s, r, q) {
            $.PageDialog.confirm(s, r, q)
        };
        if (h.length > 0) {
            h.children("a").click(function() {
                location.href = Gobal.Webpath+"/mobile/cart/pay"   //付款页面
            })
        }
        g.children("a").click(function() {

                if (!isNaN(t)) {
                    r++;

            })
        })
    };

    if (a.length > 0) {
        Base.getScript(Gobal.Skin + "/js/mobile/pageDialog.js", b)
    } else {
        c.show()
    }
});]

下面的是页面地址，点商品加入购物车后点加或者减里面的总共显示金额显示出来不对，但是提交上去的金额是对的 求指点
