Paypal Embed in Posts – Formatting Help Needed!

Hello,
I am embedding Paypal donation buttons in posts and would like them to be in the same line with some text.

When I’m embedding these it just places it on the next line and not the line with the other content. Even when I edit it visually, it still moves back.. How can I embed these where I would like them.. http://documentaries.org/2009/02/10/coexist/

Any advice greatly appreciated!

Best, David
