MSP430FR2422: function call error??

Part Number: MSP430FR2422

I am calling a function in main that exists in a second file.  The function call in main is:

configRTC(1800);

The function definition in funct.c is:

void configRTC(unsigned int s)
{
    unsigned int k, div = 0;
    if (s < 2)
        div = divB[0];
    else if (s >= 2048)
        div = divA[3];
    else {
        for (k = 0; k < 3; k++) {
            if (s > (2 * divA[k]))
                div = (k + 1);
        }
    }
    RTCMOD = (int)((float)(32768 / divA[div]) * s) - 1;
    RTCCTL = RTCSS__XT1CLK | RTCSR | (div + 4) << 8;
    RTCCTL &= ~RTCIFG;
    RTCCTL |= RTCIE;
}

In funct.h I define divA and divB:

unsigned int divA[4] = {16, 64, 256, 1024};
unsigned int divB[4] = {1, 10, 100, 1000};

When I go to build main I get the following errors:

#10056 symbol "divA" redefined: first defined in "./funct.obj"; redefined in "./main.obj"
#10056 symbol "divB" redefined: first defined in "./funct.obj"; redefined in "./main.obj"

I don't understand why main is trying to redefine these as they are local to the function only and don't exist in main. I have tried placing extern in main but to no avail?  funct.h is included in both main and in funct.c.  I can build funct.c without errors so I know my problem is with main somewhere??

Thanks
