[OpenLayers-Users] Display Coordinates

[Riggi Valerio]

I corrected the code but still I don't understand a thing.. when I go on 
the WGS-84 map (http://www.intornoamessina.it/tracking/) and I point the 
mouse at a certain point of coordinate -93.2735, 44.8349 the result is 
like 4613718.1118, 1718560.9374, should not be like the coordinates before?

Many Thanks
Valerio
