title: Passing data from multiple forms to one single form
body: <p>Is it possible to pass details of multiple forms that all lead up to one form? 
  I want that each time i click that button that leads to the next form, show the details from the form it came from.
  I have multiple forms such as newclient, updateclient and transactions that use the billing form. and I want to know if I could pass the details of each of those forms to the billing form?</p>
