CMS PayPal Buy Now button problem in CMS articles
 

I have been able to add PayPal buttons to my CMS articles, but now I can't and I can't see what I'm doing wrong. If I paste the following:
HTML Code:




<img alt=span style="color:#0000FF"""/span border=span style="color:#0000FF""0"/span src=span style="color:#0000FF""https://www.paypalobjects.com/en_US/i/scr/pixel.gif"/span width=span style="color:#0000FF""1"/span height=span style="color:#0000FF""1"/span>

After publishing, I don't get a button but instead, get this:
https://www.paypal.com/cgi-bin/webscr" method="post">

https://www.paypalobjects.com/en_US/..._buynow_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
http://woodturnerpro.com/%3Ca%20href=https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1">

In AdminCP > vBulletin CMS > Permissions, for Administratore, I have checked the box for 'Can Use HTML in CMS Content' and I've also clicked the button for HTML On - Convert Linebreaks.

Any idea what I'm doing wrong?
