image issue , please help

[#1]

Hi

i am useing google map in my qlikview and randomaly the map disappearing with no reason

i am useing this string in the dynamic image

='http://maps.google.fr/staticmap?center='
&
num(var_mid_lat, '##############', '.', ',' )
&
','
&
num(var_mid_long, '##############', '.', ',' )
&
'&zoom=$(var_zoom)'
&
'&maptype='&var_maptype
&
'&size='&map_size_x&'x'&map_size_y
&
'&key='&gmap_key & '.jpg'

i dont think that this is a FW or proxy issue , when i insert this string into a text box i am getting a valid URL and i am getting the map image in my IE.

FYI , i am useing GMAPKEY = "XX" , could it be the issue ? please help
