that simply means that the element does not (yet) exist at the time you call it.

This error TypeError: document.getele mentbyid(...) is null would seem to indicate that there is no such element with an ID passed to getElementById( ) exist. This can happen if the JavaScript code is executed before the page is fully loaded, so its not able to find the element. The solution is that you need to put your JavaScript code after the closure of the HTML element or more generally before < /body > tag.
