Hi FF
Just to add to what Daniel said correctly - you need to use the follow
hyperlink.
But you need to add some "stuff" to it to get it to ork with google maps.
Also - you need to alter the zip/post code to make google maps understand it.
Most importantly you can NOT send the link (url) direct to google and hope
it will work on the right map - it won't. So you also need to tell google
maps "which" bit of the world you want to see as you map.
Have a look at this answer I gave a while ago.

This will give you a step by step. If you have problems post answer
question and someone here will be able to answer
Good luck with your application
