Well, I have an auto\_complete to get users names, and in other forms it works great. This auto\_complete, however, it first asks the user to select an account and then pull all the users from that account, so the parameter that I need to pass is the id to the account to populate that list.

Ah. Ok. It's been a while since I used auto\_complete and haven't tested this, but it should point you in the right general direction. First though, note that everything after the first two parameters is interpreted as elements of a hash. You don't need the {} notation. The items that can appear in that hash are the parameters to ActiveRecord::Base#find. IIRC auto\_complete just passes them through to the find. You're wanting to supply the :conditions. The syntax may be wrong but I already warned you I haven't tested it. 😉

\<%= text\_field\_with\_auto\_complete 'user', 'username', :conditions =\> ["post = ?", @company\_title.id] %\>

HTH, Bill
