It works great in IE6 and Opera7, but not in Mozilla Firebird 0.6... However, it works fine in all 3 if you change line 47 from this:

if (document.all) fader.innerHTML = text_out; // document.all = IE only

to this:

if (document.getElementById) document.getElementById('fader').innerHTML = text_out;
else if (document.all) fader.innerHTML = text_out; // document.all = IE only

still the same problem.
i am thinking now it has something to do with pagebuilder (*sigh*) - a very limited online editor provided by geocities. i have to start off using this until i have hosting arranged.
are you sure adjusting the position
( <div id="fader" style="position:absolute; top:35px; left:50px; width:600px; text-align:center;"></div> )
will make no difference ?

thanks anyway

ah, i just tried putting the code on a new page, alone- without any other text or images.. and it worked.
what does that i mean i have to change?

I'm not sure what that means... I'm sure there's hundreds of things that could cause that to happen. If you uploaded it someplace and gave us a link to the page we might be able to help though...
