Google maps latitude and longitude from other side

Hi,

I want longitude and latitude extract from one fields, create variables and put to google map.

Is it possible?

This:

// name of field in table that used as latitude for map

$mapSettings["latField"] =

// name of field in table that used as longitude for map

$mapSettings["lngField"] = [color="#006400"]"longitude";
change to:

// name of field in table that used as latitude for map

$mapSettings["latField"] = ;

// name of field in table that used as longitude for map

$mapSettings["lngField"] = [color="#FFA500"]$long;

or other way?

Many thanks,

Rimantas
