Stupid garbage javascript...

I'm trying to use Share This on here, but it seems wherever I put it on the Blogger page elements it just sits there, rather than embedding in my posts. So now I've tried to add it as an element to each post, but when I went and pasted the script in, it only shows on the most recent one.

Does anyone reading this have any idea on the proper way to embed the script so it will show up properly?

Update: Apparently it doesn't work.

So I did this instead.
