Can you post your code here?

Hi yenthe,

I manage to get the register working, i realised that i need to create new folder as new modules for new fields if it was added before first installation.
Thanks a lot.

However i modified your button action demo to develop for basic calculation module. but it seems like button click and on change method doesnt seems to trigger. Hope you can help me on this. Thanks.
