"submit" Button wont work

Hello !

i tried this plugin and it works pretty well !

But i cant change the sample popup or add a new one cause the “submit” button has no function. It happens nothing when i click it, no “reload-wheel” or something else. I tried it with firefox, chrome and opera.
It just does nothing.

Any Ideas ?

Thank you in Advanced.
