Mapquest API issue when adding maps

[YohannGrosclaude]

Hello,

Base on a list of customer address I created an app to load coordonates based on the example I found in the community.

This work well but the issue I have is when I add the map in color tab.

I found that I need to use this dynamic image:

='http://www.mapquestapi.com/staticmap/v4/getmap?key='&Key&'&type=map&size='&
//def_map_size
map_size_x
&','&
//def_map_size
map_size_y
&'&pois=&center='&
num(var_mid_lat, '##############', '.', ',' )
&','&
num(var_mid_long, '##############', '.', ',' )
&'&zoom='&
$(var_zoom)
&'&rand=1212384919'

But for some hidden reason the result is that map is centralized in Somalia and I 'm not able t undertand why.

My dots are calculted correctly, I added all formulas  found in the example but this point I'm not able to explain it.

Someone already experience this and foudn a solution ?
