I'm setting up the simple donations feature

I'm setting up the simple donations feature of the Fundraising plugin and this is the code that I used:

[donate_button title="Donate Now" description="Make a donation to MWEW" donation_amount="" button_type="default/custom" style="" button_text="Make Donation" show_cc="no" small_button="no" paypal_email="mommalenewew@gmail.com"]

Nothing is showing on the page but the word "Donate Now" which you can see here.:
http://mommalenewew.com/donate/

Can you please tell me what I'm doing wrong?
