TCA6424A: I2C Communication with MSP430G2ET

unsigned char TCA6424A_ADDRESS = 0x22;
unsigned char LED_config1 = 0x84; //LEDs 1-4
unsigned char LED_config2 = 0x85; //LEDs 5-12
unsigned char LED_config3 = 0x85; //LEDs 13-20


short value = 0xF300;
//short value = ReceiveBuffer

int main ()
{
    WDTCTL = WDTPW | WDTHOLD;    // Stop watchdog timer
    unsigned char regVal = 0x10;
    I2C_Write_Byte(TCA6424A_ADDRESS, LED_config1, regVal);
}

Based on the code included I'm seeing a couple of errors, I can't seem to find a solution for the issues I'm seeing.
