If you edit some page of http:\\bn.wikipedia.org\ in IE, you can see the "Phonetic Bangla Typing. Check/Uncheck box or use Esc as a toggle key to activate/deactivate. Go to WP:Typing for help". That means the script is OK. But you can't see the same in FireFox.

I found an error in error console Error: [Exception... "Node was not found" code: "8" nsresult: "0x80530008 (NS_ERROR_DOM_NOT_FOUND_ERR)" location: "http://bn.wikipedia.org/w/index.php?title=-&action=raw&smaxage=0&gen=js&useskin=monobook Line: 1277"]Source File: http://bn.wikipedia.org/w/index.php?title=-&action=raw&smaxage=0&gen=js&useskin=monobook Line: 1277 at editform.insertBefore(element,textBox); Do you Know where Node has to be define?

Clarified summary line. Note that the phonetic keyboard goodie is a local JavaScript tool; it may have been affected by recent changes to software or may have been changed, or may just be broken as-is and needs some debugging.
