Ruby on Rails

I am using Ruby 2.0.0 and Rails 3.2.16.

>>I get following error after clicking on "Add to count" button :

ActionController::ActionControllerError (Cannot redirect to nil!):

app/controllers/line_items_controller.rb:53:in `block (2 levels) in
create'

app/controllers/line_items_controller.rb:51:in `create'

I attached code of line_items_controller.rb and full trace of error.
please find it.

>Error occur at following line as display in error:

format.html { redirect_to @line_item.expensescounter } #line No:53

I attached full trace of error. please find it.

Any help would be appreciated.

Kind regards.
