Collection_Select not showing Selected option

Hi, I'm having some problem with getting collection_select to return
the current value when editing a record. According to everything I've
seen, there was an issue but it's been fixed, but I can't figure out

%></td>

Your instance variables is called @drivers, so the first parameter to
collection_select must match, i.e. be :drivers (although in this case
it looks like it would make more sense o rename the instance variable
to @driver
