Incompatibility with Internet Explorer 6

[Aflate]

I developed a website using a mixture of Dreamweaver CS3 and Dreamweaver CS4. The problem is that while the pages seem to be loading fine in other browsers such as Firefox, it doesn't seem to work properly in Internet  Explorer 6 (I dont have 7 so I cant test if it works there). It works fine on IE8 though. Unfortunately a great part of the target market here in South Africa can't access the website because they are still using old browsers.

The website I am having trouble with can be located here: www.associatedequipment.co.za

Are there any tips on how to make this site compatible with old versions of IE6 and 7?

IE6 has a lot of issues.  Write conditional css statements 
that target the older browsers to correct issues.  
Use dreamweavers  built in browser check to see if 
it can identify issues as well.
