want to output the result of the if statement (which is undefined and
apt to create crazy things). Try making that "- if flash[:error]".

I'm a little confused. Why wouldn't this happen? If you're rendering the
entire partial, wouldn't you expect the entire partial to show up?

See above comment about "-" versus "=".
