Hi there, I'm Stefano, the owner of the website and I'm in charge for the application form debugging.
The App is currently working and has been tested on Firefox and Explorer.
The App use simple html and javascript. Javascript have to been active:
Firefox --> Preferences --> Contents --> Activate Javascript
Explorer --> Tools --> Options --> Protection --> (Search and check the Script allowance)
If you use software like script block and simila please allow the script associated with the page.
Otherwise please try with a different browser.
If the problem persist, please tell me which browser and version are you using and I'll try to solve the issue as fast as possible.
Thanks for your patience,
Stefano
