Internet Explorer is truly evil.

I avoid web development.  It is just much more of a pain in the rear end
than it should be.  When I do web development, I test in Firefox.  I
write valid XHTML and valid CSS.  When I have to get something to work in
Internet Explorer, I curse.

So for future reference:


error: invalid character

can happen when one of the scripts which you reference does not

<script src=”scriptaculous.js” type=”text/javascript”>

oops, scriptaculous.js doesn’t exist.  Thank you Microsoft for writing
such excellent and accurate error messages.  The quality of this software
continues to astound me.
