I am attempting to put an Amazon Affiliate Link on my Wordpress website. When I put the Iframe code:
<iframe src="http://rcm.amazon.com/e/cm?t=silvars-20&o=1&p=12&l=ur1&category=amazonhomepage&f=ifr" width="300" height="250" scrolling="no" border="0" marginwidth="0" style="border:none;" frameborder="0"></iframe>
into a basic HTML file, it displays fine. When, however, I try to put it into the HTML portion of my wordpress page, it displays the error:
In the basic HTML, the IFrame source is this:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <body topmargin="0" leftmargin="0" marginheight="0" marginwidth="0"> <map name="boxmap">   <area shape="rect" coords="638,78,728,90" href="http://www.amazon.com/gp/dra/info" target="_top">
But in my Wordpress IFrame source, it seems to oddly wrap the HTML in a "document.write" tag:
document.write("<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"> <html> <body topmargin=\"0\" leftmargin=\"0\" marginheight=\"0\" marginwidth=\"0\"> <map name=\"boxmap\">
I know this is an odd issue, but I was wondering if anyone could help?

Thanks guys!
