Browser Compatibility

Okay, at work I was told to figure out why this website is not viewable in many browsers. http://www.superiornutritionandhealth.com/ (yech, don't like the website) but it does look like it should be browser safe to me. Can somebody help me out?

 

Works fine in Safari

 

Thanks, but I was told it doesn't work in 85% of browsers.

 

well if it works in internet explorer that is nearly 85% of browsers;

Test it on Opera, netscape, IE, Firefox and safari and that should be fine.

 

Looks fine in FF.

 

Thanks, I downloaded Opera and I know it works in Internet Explorer and Netscape.
