I just tried it from the controller and gives me same error message.
CONTROLLER
@durations = {"30 minutes" => "30", "1 hour" => "60", "1 hour 30
minutes" => "90", "2 hours" => "120"}

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.map
Extracted source (around line #20):
17: </div>
18: <div class="field">
19: <%= f.label :duration %><br />
20: <%= f.select ("duration", @durations.map {|d| [d.id, d.name]},
:prompt => "Select") %>
21: </div>
22: <div class="field">
23: <%= f.label :cost %><br />
