Sorry for the confusion - I have a bit of it myself! What I need to do is: if I have 2 sites, each identified by latitude and longitude (decimals), I would like to perform a calculation based on the lat/long and return a value of distance between the 2 points - and then have that value converted to either feet or miles(preferred).
So I don't need to calculate lat/long- we already have that- its to calculate the distance between 2 points.
Thanks!
