I am attempting to add a paypal button to my event post, but every time i enter this text:

<form action=”https://www.paypal.com/cgi-bin/webscr&#8221; method=”post”>
<input type=”hidden” name=”cmd” value=”_s-xclick”>
<input type=”hidden” name=”hosted_button_id” value=”PQHKMMPWAFUXG”>
<input type=”image” src=”https://www.paypalobjects.com/en_US/i/btn/btn_buynowCC_LG.gif&#8221; border=”0″ name=”submit” alt=”PayPal – The safer, easier way to pay online!”>

</form>

and click ‘Update”, the code is changed into this:

and the button does not appear. Adding the code html markers before and after does not fix the issue.

Is there something I am doing wrong?
