when imap is loaded, coordinates are lost

I’m trying to post an imap to my blog. It’s an image that has 3 hotspots attached to it, and when you click on a hotspot a pdf file loads.

All the files have been uploaded to their respective directories. I’ve pasted the code into the HTML editor window and then I click Save. However, when I go back to edit the article and I look at the HTML code, the coordinates have disappeared, and so, consequently it doesn’t work. Any suggestions?

The code is below:

<p><img src=”http://www.myurl.com/images/housesys.jpg ” usemap=”#housesys” border=”0″ />

<map name=”housesys”>
<area shape=”rect” coords=”20,142,326,281″ target=”_BLANK”

href=”http://www.myurl.com/files/Geothermal.pdf ” />

<area shape=”rect” coords=”196,54,121,5″ target=”_BLANK” href=” http://www.myurl.com/files/SolarElectric.pdf&#8221;

/></map></p>
