Hotspots and slices not working online. I can only use CSS
 

Hi I am having trouble with the hotspots tool and slice tools in photoshop extended cs3 and fireworks cs3. I get a hotspot or a slice and it works fine until I put it online then it doesn't work. I can't use XHTML to make it work because I am working with myspace profile 2.0 which does not allow XHTML just CSS. Any tips would be helpful!
