If you want a neater way of validating your form you might want to take a look at jquery validate plugin.

On submit do the following...

var formValidationRules = {
    rules: {
        date: {
            required: true
        },
        rate: {
            required: true
        },
        box: {
            required: true
        },
        (... more form fields)

    }
};

$("#ps_entry").submit(function(){
    $(this).validate(formValidationRules);
});
