I'm not sure what the error that you're getting is, but there are
enough in this fragment to go around.
- select_tag shouldn't be followed by a comma; written that way, you
are calling it without arguments.
- select_tag requires the first argument to be the name of the field
- the final argument to options_for_select is positionial; the
"selected = " part is not required (nor is it meaningful). Similarly
for html_options. The only thing that both statements will accomplish
is setting local variables to the various array values.
- keys in the options array are traditionally symbols; not really a
bug, but a slightly incorrect idiom.
