Hi All

I have finally been pulled into the world of Google maps and math is not one of my strongest talents. I have been doing some research and I am quickly getting over my head so I am hoping someone can give me some help. I know the coordinates from a GPS unit and now I need to find all addresses in a database that are within xx miles from those coordinates. A square is good enough. I need to keep it simple. The values in the database are stored in decimal xx.xxxxx format.

Thanks for your help.
