Thank you all for the replys.

I updated the code to include a check to verify the last point has
been coded, as suggested by Andrew.  It appears to be working.  I have
only tested it with 6 locations, and it is working.  I may include a
little message that says something like 'points loading'.

I am aware that this is not the best method for a large number of
points. I plan on adding some code that will cache the long and lats
for future use.  Currently the most this would need to handle is
around 15.  I plan to use the HTTP geocoder to load the position
information of a site the first time a user opens the database entry.
This should put off the load over time.  Unfortunately I dont really
know how to use JSON information, but I will eventually find out.
