I'd get away from building the HTML table manually.
I'd store the info in a datatable and bind the table to a grid (or
repeater). When legs are added, they get added to the datatable which
you can store in a session variable or database, and simply rebind the
grid to the updated table. This would cut out 90% of your code.
