Linked check boxes with a twist

I have three check boxes: Toilet, Sink and Shower. Toilet needs to be able to be checked when neither of the others are. However, if either Sink or Shower (or both) are checked toilet must also automatically be checked. Is there some way to link these boxes to do this?

As the Mouse Up event of Sink and Shower enter this JavaScript code:

if (event.target.value!="Off") this.getField("Toilet").checkThisBox(0, true);

Be aware that this does not prevent the user from un-checking Toilet. If you want to do that then you would need to set it as read-only when one of the other two boxes are checked.

Another solution is to use a calculation script on a hidden text field. That way you capture all the checking and unchecking actions, and can set the checkbox values appropriately in all cases. Including setting the readOnly to prevent unwanted entries.
