MSP432 RTC programming

Hello,

I want to program MSP432 RTC, my code is as follow:

const RTC_C_Calendar currentTime =
{
        0,
        25,
        11,
        4,
        28,
        1,
        2016
};

I initialized RTC as shown above, Now I want to reprogram it using the structure which is shown as follow:

currentTime.hours=Rxhours[0];
currentTime.minutes=Rxminutes[0];;
currentTime.dayOfmonth=Rxdate[0];
currentTime.month=Rxmonth[0];
currentTime.year=Rxyear[0];

It sows error saying "#138-D expression must be a modifiable lvalue" I dont know the proper syntax to be used. Can anyone please tell me what is the proper syntax?


Here Rxhours[0],Rxminutes[0],Rxdate[0],Rxmonth[0],Rxyear[0] are the buffers where I store the time taken by the PC

Regards.
