Is there a way to add a paypal donation on to my yahoo 360 blog?

paypal provides the source code to add a on for donations. however, i am not sure how to add the on. i use an apple computer running the latest edition of OS X. I would like to place the on in the area currently occupied by the calendar. Can anyone help me. I wish to collect donations for the building of libraries and school material for kids that do not have the opportunity to attend school in the countryside of china. thanks
