Hi Deb, there shouldn't be any compatability issue with wordpress at all. Are you trying to install it in a blog post or in the sidebar?

It won't install in a post, generally, unless you're able to code around it to force display - blog text editors don't understand code (they're just designed to display text, links, and images, so an application wouldn't translate well in your text editor - I'd suggest installing the calculator in the sidebar of your blog instead (the mini should fit perfectly.) If you're already trying to install in the sidebar and that's where you're having troubles let me know and we'll help you figure it out
