browser incompatibility, page looks different in different browsers

[jpete]

HELP, please visit http://www.emainline.net/franciscan/who this is a web page still in beta but the problem is it looks different when viewing on a macintosh and not for the better, what can be done to ensure wide browser compatibility, is there a decent website I can run a check on it, the ones I found on google either dont work very well or want $ to do the check.

DESPERATE for some advice

A few points...

It's better to use lower-case.
Change this :
<SCRIPT language=JavaScript type=text/JavaScript>to this:<script type="text/javascript">
Any values should be in quotation marks i.e. not like this : <TABLE cellSpacing=0 cellPadding=0 width=1004> but like this : <TABLE cellspacing="0" cellpadding="0" width="1004"> (Although I'm wondering if you really wanted a table that wide...)
Having said that, this stuff - things like 'width' - should go in css rather than the html (although a Transitional doc-type does allow it).
Not a problem, but you can do rollover image-swaps more cleanly in css - like this (http://bonrouge.com/br.php?page=rollover2).
