Forum:Edit Summary Javascript Help

Hello I am EdBoy3, an admin at the Beyblade Wiki. I would like some javascript help so let me explain. At The Sims Wiki, they have this Edit Summaries feature that can be scrolled to reveal summaries that tell about the edit you're doing. If you don't understand what I'm saying click this link, it's what's under the Edit Summary box that says (click to browse).

Now I know that this request may sound ridiculous since there is already an Edit Summary box, but I like this one as it makes it easier to put summaries and our community likes it.

The problem I'm having is that although the coding from these pages has been added to these pages from Beyblade Wiki, even though the feature itself actually appears, it does not reveal the actual Edit Summaries and I don't know what I did wrong. I copied the coding correctly though. So I hope you can please see what's wrong and fix this for me, thank you in advance. :) User talk:EdBoy3

PS: This shows how it does not work. Note how it does not reveal any Edit Summaries and does not state (click to browse).
