Jquery Validator - need to add a method

Hello all,

I am still struggling with the ins and outs of this plugin:

http://bassistance.de/jquery-plugins/jquery-plugin-validation/

Now I need to add a method because I don't believe there is any existing method to do this.

I need to check several different fields in a form to make sure they are not all empty. Two select fields and one text field. Can anyone help me with this? How can i add a method that is for the entire form, which will then look at the specific elements I need it to, to check to make sure all three are not blank?

Thank you!
