Conditional Formatting problem
 

I have a file that has three levels of conditional formating and in
the native format everything works fine, However, when I save the file
in HTML format, the cells and and colors get all out of whack. Some
don't show and some show on cells that don't meet any of the
conditions. I have temporarily overcome by formatting the cells but I
really would like to use the condtional and let Excel do the grunt
work, Has anyone ever seen this problem or have an idea how to fix it?
