Mootools Form.Validator checkbox

[electronbender]

I want to validate a checkbox. Actually multiple ones with one and
same name:

<input type="checkbox" name="somefield" value="1">1
<input type="checkbox" name="somefield" value="2">2
<input type="checkbox" name="somefield" value="3">3
I want to make sure at least one box is checked before the form is
submitted.

So i've added a validator:

Form.Validator.add('isChecked', {
errorMsg: 'One of these fields is required',
test: function(element){
if (element.type == 'checkbox' || element.checked==true)
return false;
else return true;
}
});
But that requires all fields to be checked...

In the least case i want to pop out the same Form.Validator.Tips error
message (cant figure out how that is fired)...

So how do i go about dealing with this?
