Will not show html code

I want to have some html on my site, so other people can use one of my banners, on their site. I used the simplecode from her http://www.tamba2.org.uk/files/simplecode.php?mode=process

I generated this code with it :

<a href="http://jimboscorner.dk"><img src="http://jimboscorner.dk/bbbanner180x150.jpg" style="border:0px;" alt="Blogbuster" /></a>

And the output was this:


<a href="http://jimboscorner.dk"><img src="http://jimboscorner.dk/bbbanner180x150.jpg" style="border:0px;" alt="Blogbuster" /></a>


Then i pasted the output to my WP 2.0 page, that i made specialy for banner.

But there seems to be an error, because when save the page the outcome has changed to this:

<a><img xsrc="http://jimboscorner.dk/bbbanner180x150.jpg" style="border:0px;" alt="Blogbuster" /></a>

What makes the x marks before ‘href=’?

The bannercode is for copy and paste purpose.
