liveEstimatePHPCode.php creates a form to collect inputs from a client and then calculates the estimated courier charge based on the type of vehicle and the distance using UK post codes. iaf-plugin.php appears to create a widget (i.e. it appears in the widget menu) but when added to a page nothing is dispalyed.
