Tom,

In &Vend::Order::route_order, the main routine for processing the order 
routes, you'll find this happens before each route is run:

     my $value_save = { %{$::Values} };

and then after each route runs, this:

     $Vend::Interpolate::Values = $::Values = { %$value_save };

That keeps any order route from changing values space in a way that 
affects the rest of Interchange. It's also usually not what you'd expect.

My guess is that something in your log_transaction order route is setting 
values, which are put in the database, but then reset before you use them 
in your receipt page.

You could test this theory by storing your city in a scratch variable 
(since scratch isn't reset in routes like values are), and using that 
scratch variable on the receipt page.
