If you are referring to this, as explained by AnnabellRice on the edit summmary, your addition was unreferenced.

References play a key role in making our site a reliable source of information, so it's required you reference the information you add to a page. To place a reference at the end of a sentence you've written, you need to put between the name of the article of the comic/movie/episode where the events you described happened. It looks like this:

Peter Parker was bitten by a radioactive spider.
