validate box for 2 numbers

[crosemffet]

hello, and thanks in advance for your support.
I have 2 field numbers:
<input class="easyui-numberbox" id="bet" name="bet" value="">
<input class="easyui-numberbox" id="price" name="price" value="" validType="greaterThan['#bet']">
I need to extend the validate box to check than price is greater than bet.
That's what I'm doing:
$.extend($.fn.validatebox.defaults.rules, {
    greaterThan: {
        validator: function(value,param){
            return number(value) > number($(param[0]).val());
        },
        message: 'Price must be greater than bet.'
    }
});
not working.
what's wrong?

Try this code instead.

Code:

$.extend($.fn.validatebox.defaults.rules, {
    greaterThan: {
        validator: function(value,param){
            return parseInt(value) > parseInt($(param[0]).numberbox('getValue'));
        },
        message: 'Price must be greater than bet.'
    }
});
