jQuery :(
I wish Rails wasn't so intimately tied with Prototype+scriptaculous. It makes jQuery that much harder to use. Even so, using page << and jQuery is much easier than trying to use Prototype to achieve the same end. Not to be a fanboy or anything, but is there any other library out there that can remove a specific option from a dropdown select box in one short line of code?

I'm using Ruby 1.8 and Rails 2 for this.
Thanks to BigSmoke for both the ActiveResource::Errors hint as well as inspiring me to look for another way.
What this method does is create and populate an error div with the specific error messages that occurred, and then destroy the div when the user submits a valid entry.
