Paypal quicktag not working?

How can I get either the html code generated at the paypal site to work in a page generated through WP, or the paypal quicktag to work on same said page? I actually don’t care by what method this is accomplished, as I simply want to have a button which links to the paypal site so I can get some sweet moola from family and friends. Here is the page that I got the quicktag script from:

I changed the tagStart line to this:
ed15.tagStart = ‘<!–paypalbutton–>’;
I inserted <!–paypalbutton–> in the page, but no link. (Link to page below)

I tried just inserting this code from the paypal site:
<form action=”https://www.paypal.com/cgi-bin/webscr&#8221; method=”post”>
<input type=”hidden” name=”cmd” value=”_s-xclick”>
<input type=”image” src=”https://www.paypal.com/en_US/i/btn/x-click-but21.gif&#8221; border=”0″ name=”submit” alt=”Make payments with PayPal – it’s fast, free and secure!”>
<input type=”hidden” name=”encrypted” value=”—–BEGIN PKCS7—–(ENCRYPTED DATA YADA YADA YADA—–END PKCS7—–
“>
</form>

to this password protected post page: (PASSWORD IS “donate”)

The button just goes to the paypal site and it comes back with an error saying that the paypal site is having problems. The only problem is that the WIKI site has a paypal donate button and it gets to the Paypal site successfully. I suspect there is a problem with my code, as it is HTML, not XHTML. Can anyone help me find the correct tag? I only need this on one page of my site.
