I went to linkshare to get banners for my web page - I inserted them using Dreamweaver CS4 in the begining of my page title of my index page. I used a validation tool to check my web site. Over 100 errors just from inserting 5 banners. The web page looks fine.

I noticed however after telling DW to cleanup the code it did the following: IMG now begame img and it also added "&amp" without the quotes in a few places where the banner links are. So now DW says everything is ok but the validation tool says there are some more errors still remaining.

I'm confused - I would think if I get a link from a banner site the link should be clean and free of errors. If I let DW clean this up, will the banners still work? I understand I can not click on banners on my own web site and should I be concerned with this at all? I assume yes. Ok I only started trying to build web sites one month ago, so I'm new to this.

Thanks,
Andre

Without seeing the page I can but guess and I guess you attempt to write XHTML, where all element and attribute names must be in lower case.

Ampersands in URLs should be escaped with &. Yes, the links will still work.
