jquery validate, check difference between fields

jquery validate, check difference between fields

Hi all,
I'm new to jQuery. I use the plugin validate in order to check values between two fields.
So I have two fields, and I want to check if the value of the first field is greater than the value of the seconde one.
But, I can't find into the documentation how to do that.
Following is my current JavaScript :
  1.     $().ready(function() {
            $(document.CorrespondancePPForm).validate({
                rules: {
                    tpsRetenu1: {
                        required: true,
                        number: true,
                        min: 0,
                        max: $(document.CorrespondancePPForm.tpsRetenu2).val()
                    },
                    tpsRetenu2: {
                        required: true,
                        number: true,
                        min: $(document.CorrespondancePPForm.tpsRetenu1).val()
                    }
                },
            });
        });
















As you can see, I tried to do it by "min" and "max" rules.
Can anyone help me ?
