I am sorry that I have to post this question, but I am working on a
project and I can`t proceed before I have finished the maps section.

I am only in the maps API for a few days now, so i started with the
basics. Some tutorials and some experiments.

Than I found for what I tought was the tutorial I needed. The store
locator. I followed the tutorial and this http://www.mijngroenteboer.nl/maps.html
is what I came up with. But After aprox 32 hours of reading a lot of
discussion and working the code. I am unable to get the script to work
like I want:

A user enters an adress or zip code and the map shows the markers
close (radius 10 - 20 km) from his adress. My map now does the math
from the center of the map instead of the adresse of the visitor.

I am running PHP 4.4.7

Looking forward to your advice.

Thanks in advance

Kind regards.
