Reply To: Make the Adult field 0 instead of 1

Search the whole plugin for $_POST[‘persons’] and replace it with your custom field. Then go thought the ajax functions in js/ajax/ and replace all selectors of the persons fields with your fields id. And probably there are 10 other things to change I don’t think about jet. That’s why I say it’s not possible, it’ll take long to find all these places and then you have to change it correctly to not produce new bugs….
