Distance calculating function problem

[ukscotth]

Hi,

 

I have been using the following function on my server and it works fine but when I try and use it on a different server it wont seem to work. Any ideas on why it wont work on the new server and any ideas on how I can do some error checking to figure out why ?

 

Thanks in advance,

 

Scott

do you have the same version of php on each server.
