MSP430FR2355: driver scope issue??

Part Number: MSP430FR2355

Hello....

I have a structure in a driver that I am trying to assign values to via strncpy....When debugging with a breakpoint the source looks fine, however the assignment to the destination never takes place....All destination contains 0xFF.  I  am not sure how to do assignment correctly and I want to be able to use the values from the structure in main.  Here are "what I believe" the pertinent code pieces.  I seem to be struggling with scope issue ....

main.c (declaration and function call....no definition here as it is assigned in the driver??)

gpsMssg_s *pGPSData;

GPSMssgParser(pGPSData);

driver.h 

typedef struct gpsLogValues
{
    char utc[15];
    char latitude[15];
    char longitude[15];
    char date[10];
    char satellites[3];
}gpsLogValues_s;


typedef struct gpsData
{
    gpsLogValues_s *gpsLog;
}gpsMssg_s;

driver.c (assignments)

                    strncpy(pGPS_d->gpsLog->utc, &NMEAData[7], 10);
                    strncpy(pGPS_d->gpsLog->date, &NMEAData[57], 6);
                    strncpy(pGPS_d->gpsLog->latitude, &NMEAData[20], 11);
                    strncpy(pGPS_d->gpsLog->longitude, &NMEAData[32], 12);

NMEAData looks fine at breakpoint....just can't seem to get the assignments to stick....????

Thanks
