Code Location

.pl file: /afs/

country code file : /afs/

html page : /afs/


The form is hard coded in so the Metric, From, To, Year can get out of date. The metric and year both do not change much and are only referenced once (metric) or twice (year) in the form and so can be easily updated. Keeping up with new From and To is more problematical. Today one has to edit the html page (see above).
