...not because you did anything wrong, but because you appear to have made the changes using the Visual Editor, and the Visual Editor has been known to corrupt the source for pages on which it's used -- which is what happened in this case. If you would like to resubmit your edits using the Source Editor they'll likely get almost instant approval. If you didn't save a copy of your edits, we can recover them, and either insert them for you or make them available for you to resubmit.
Let us know what you want to do.
