1) You have a dot between the getElementsByTagName call and its
parameter list.
2) The function returns an array of elements. You need to loop
through them and disable them one by one.

There is no function getElementByName for the document object. You
might have meant getElementsByName. You should probably use the
dollar function $('commit') [1] anyway, and use ID's instead of names.
Anyways, to find out what's wrong, I highly suggest getting the
FireBug [2] Firefox extension. With it you have a lot easier to debug
your scripts.
