User blog:DerrickSheldon24/Clickety-Clack, Clickety-Clack!

I have a problem on Between the Lions Wiki, it's about the Clickety-Clack, Clickety-Clack! article. You see, I'm trying to rename it because it's first called Clickety-Clack but I want to rename it to Clickety-Clack, Clickety-Clack! because that's the real title. But when I do that, I got a warning that says "This can be a drastic and unexpected change for a popular page; please be sure you understand the consequences of this before proceeding", the screen also says that I don't have permission to do that and it thinks that the name I try to use is valid but I think that it's not. Please help me fix it, and here's a Youtube video link of the episode, https://www.youtube.com/watch?v=XCBygV1aqX0 and here's a link of the rename part of the article, http://betweenthelions.wikia.com/wiki/Special:MovePage?action=submit
