How to exchange user data with the same class instance

Hi Woutrr60 not quite the current solution posts the data for the step to a different function in the controller. The design is effectively a function for rendering the form and the one for storing the new data. One further question if I may? The start process displays the first view and in the process instantistes the controller class instance ( I think). If I then post the form to another function within that controller am I right in assuming this is a different instance or does it magically find the original instance? In the latter case I would expect the class variables to still be set? As I said I’m wallowing a bit in the detail here alas so any enlightenment wouy really be appreciated, regards Paull
