Calculated distances

Hi Mike

Good question! We are actually looking into this ourselves and there is quite a bit to consider:

Do you "buy in" 3rd party code to save time? if so is it fully tested, do you need to source post code references separately?
What is the code written in? (php, vb, etc)

You can do a search on google for "postcode distance calculator code" and get some relevant results.

We are still looking for a solution to fit our requirements, good luck with yours!

Regards

Jacob
