MESSAGE DIALOG BOX

I think this should be fairly easy although I am not sure.  I want to have a message dialog box appear everytime two check boxes are checked at the same time that tells the enduser that by doing this they could be restricting there search.  I have the dialog box however it comes up whether they have one, two, three or however many checkboxes checked.  How can I make this only happen when they have more than one checkbox checked at the same time?  Example would be appricated.  If this is more difficult than 25pts I am open to giving more for a good answer.
