GPS data not posting to sparkfun data pages

i doing gps program using fona libraries lonet gps/gprs card
im getting gps fix , gprs connection getting gps data not sure how pass on sparkfun data services. i'm getting readout in serial monitor of location when try , pass sparkfun showing lat 0.00, lon 0.00 heading 0.00 speed 0.00

to make lonet card work had edit of @ commands in fona libraries (but @ commands nothing else)

the readout shows value of latitude, longitude, heading, speed_mph

code: [select]

<--- +cgpsinf: 32,203559.000,a,5146.9829,n,00129.3548,w,0.000,354.02,180915,,,a
gps lat:51.783046
gps long:-1.489247
gps speed kph:0.00
gps speed mph:0.00
gps heading:354.02


but when try post values show zeros

why values doing this??
thanks in advance

stupid! read on scope. now!
