The page in question is:
http://www.mnsphoto.com/test/00-cook...ster_page.html
The page validated with no errors prior to placing the Amazon.com advertising block. After much fighting with the Amazon code, I have the problem reduced to 4 errors, all of the same type: the validator says that there are four 'extra' </iframe> statements, one for each version of the Amazon code included in the javascripting.
If I remove all of the </iframe> statements, the errors go away, but the page display is interrupted after the Amazon ad is displayed and no more is displayed.
If I leave at least one of the </iframe> statements, I get a validation error for each one left in.
Can anybody help?
