Will not show up on my site

Hello! I am trying to use this back to top on my blog: http://www.dreamalittlebigger.com/

I’ve installed and set everything as I’d like it to be but it won’t show up.I’m thinking that it might be a conflict with another plugin but I don’t know for a fact. Any thoughts? I could send you a list of my plugins if that would be helpful.

I like your button the best so I’d love to use it. Thanks so much 🙂
