Thank's Chuv , I did some more studying on the problem last night, managed to find a conversion program that I can understand.
On the subject of the standards used by the Geocache site are they clearly identified on the site, I looked but could not find any clear reference to them, this is a problem I have found with other sites they seem to assume you automatically know what standards they use and the issue only seems to be dealt with in FAQ's section if at all.
Regards,
Steve.
