Can't edit a post

I wanted to edit a post because a link in it is pointing to the wrong spot but I can't for some reason. In this thread: http://androidforums.com/motorola-droid/25586-verizon-insurance-plan.html#post173296
my first post (#13) can't be edited, but my second post (#26) in the same thread can be. Just wondering what would cause that.

 

The link in that post doesn't go to the right page when it is clicked. It should point to http://androidforums.com/motorola-droid/19581-droid-insurance.html#post125019
