Re: Validation Question/Form Question

first you need allowEmpty => true for your radio buttons
then, you simply need a custom validation rule for the 'other' field

'other => array('rule'=>array('checkOther'));

function checkOther() {
if(///check if radio buttons are empty && 'other' is not decimal///)
{
return false;
}

return true;
}
