How can I embed a donation button into a Wordpress.com webpage?

I want to place a "Donation" button that is linked to a paypal account into a website I've setup through Wordpress.com. When I go to the "embed" process in Jotform, I see the message clearly stating the jotform button I've created will NOT work on Wordpress.com. Is there an alternate way through Jotform to do this, or do I need to contact Wordpress.com and get their advice on how to proceed?

The wordsite I'm trying to place this "donation" button into is at www.reddragoncordova.org

Hi,

There is actually a bit different method for embedding your form into a Wordpress.com page.  Here is our guide on how to do so:

The two processes described in that guide should allow you to embed your form.  If they do not, let us know and we will be happy to see what else we can do.
