IE getElementById Bug #
If there are two elements in a page with the same name, say for example a hidden field and a meta tag, Internet Explorer won't let you get one of them by ID. Why? Because IE is stupid.
The solution: for form elements at least, you can fall back on old school antics such as document.FORMNAME.elements["fieldName"], but it would be advisable to wrap that in a function so that somebody on your team (or yourself a month later when you've forgotten the problem) doesn't come along and replace the old code with a $() call.
Code sample: TODO. (if a simple test case fails to reproduce the problem I'll delete this post, but I've encountered the issue twice now, so I think it will)

Yeah, this is very reproducable whenever an element with a name attribute appears before the element you want, but the name matches the id you are looking for.But GOOD NEWS! there is a fix for this! Buddy over at this site:
