Hi Fred, Thanks for taking the trouble to respond again, especially since I failed to follow your previous response. The problem then was that I was unsuccessful in applying it or didn't understand it ... probable both. I definitely failed to realize that the argument (object) was to be omitted in the context of form elements. That "little detail" seems missing in ActionView::Helpers::FormOptionsHelper. Someone explicitly mentioned that in a subsequent post on this thread.
Sadly, when I followed your suggestion "to the letter", I was unsuccessful again. I've got: ====== Error Msg ========= NameError in Expenses#new Showing app/views/expenses/new.html.erb where line #13 raised: undefined local variable or method `vendor_id' for #<ActionView::Base: 0x4822310> Extracted source (around line #13): 10: 11: <%# New version of vendor selection -%> 12: <% @vendors = Vendor.find( :all, :order=>"nickname ASC") -%> 13: <%= f.collection_select(vendor_id, @vendors, :id, :nickname) %> 14: <%# End of New version -%> [snip] ====== Error Msg ========= So I tested whether vendor_id would be defined if I created an Expense instance in Rails console: Here's what I got (edited for brevity): K:\_Projects\Ruby\_Rails_Apps\_EIMS\RTS>ruby script/console Loading development environment (Rails 2.3.5) >> expense = Expense.new => #<Expense id: nil, vendor: nil, description: nil, category: nil, [snip] >> expense.vendor_id [NoMethodError] >> Expense.vendor_id [NoMethodError] >> params[:vendor_id] [NameError] I also tried using the symbol :vendor_id as the first arg. That failed, too. I apologize for being so obtuse. But I'd really like to get this app working, and getting this expense-vendor hookup working may be my last obstacle (for a while, anyway). If you can give me a little more help about this problem, I'd be most appreciative. If you need more info, I'd be happy to post portions or all my code to a website from which you could download it for inspection.
