Thread:Project:Support desk/Trying to make a widget: Checkbox table

Dear friends,

I am trying to create a widget, and somewhere I am missing few codes. Being of medical background, I have very limited knowledge about computer languages (java, media wiki) and any help would be deeply appreciated.

I want to incorporate this widget (http://en.wikipedia.org/wiki/Widget:Chad_score) to this page (http://en.wikipedia.org/wiki/CHADS2_score). Please let me know where I am going wrong. Thanks a lot.
