Not a problem chowhound
I have everything with the exception of the "Profile Index" running XHTML 1.0 transitional compliant right now on my test site. I also had to remove some empty color attributes in the standard infopop.css file so that it validated. There were warnings that I didn't include background colors with forground and vise versa but it validated none the less.
I also had to remove the code in the header.php include that is already present as it was not compliant.
The Profile Index was the hardest one for me to convert on the version I should be working on now and I really don't want to fix this older version... lol but I will. It was because of the way I'm tracking what check boxes are checked.
Once this version is smoothed out it should render well in all browses... *should*
