ok no problem, thanks anyway.
Basically i have rewritten a quick script that does the conversion
which is below.
Now this script adds the marker fine but the conversion is completly
off, if i put the lat, long in manually which i know then it displays
correctly but if i let it pick up the variables long and lat that have
been converted then it goes in a completly different place.
Maybe you can help with this one.
Many Thanks
Tom
