Its happening because (as someone pointed out in a previous reply) the DOM node
does not exist yet .....
you need to wrap the code in observers...
for example...
Event.observe(window,'load',function() {
$('TheElementToHideObserver').observe('click',function() {
$('firstname').hide();
});
});
//Then your html
<input type="submit" id="TheElementToHideObserver" value="Hide First Name" />
<hr />
<input type="text" name="firstname" id="firstname" />
....
Simple as that

Subject: [Proto-Scripty] Re: Some basic basic stuff
I never put in a name attribute, that could be part of the problem.
I solved it by putting it in a function that's called by onclick, and it
worked. I was able to reference it the old fashioned JS way, and prototype's
way.
Now all I want to know is how to load and parse a JSON file using the same
method.
Thanks!

Try naming the ID attribute different than the NAME attribute.
