From version 1.4 you can use pagebreaks in your form.
In this case we use it to let people check their name and companyname. After selecting further, the next page is presented.
People can fill in their “winning number” and the result is shown; whetter they won a price or not. Depending on the browser the also added feature is that; or the browser-backbutton is disabled, or they go back to the first questions. We noticed in earlier campaigns that winnings were not saved using the browserbackfunction.
