LAUNCHXL-CC1312R1: Sensor controller studios task testing error

Im going through the "project from scratch" from SimpleLink Academy - 3.40.02.01 in the resource explorer, and have an syntax error/unknown identifier pop up in  the task testing window in sensorcontroller studio.  i am fairly new to the program but i have no idea what is wrong.

here is the code

// Enable the ADC
adcEnableSync(ADC_REF_FIXED, ADC_SAMPLE_TIME_2P7_US, ADC_TRIGGER_MANUAL);

// Sample the analog sensor
adcGenManualTrigger();
adcReadFifo(output.adcValue);

// Disable the ADC
adcDisable();

U16 oldState = state.high;
if (input.adcValue > cfg.threshold) {
    state.high = 1; // High input - > High state                this is line 13
    gpioClearOutput(AUXIO_O_GREEN_LED);
} else {
    state.high = 0; // Low input -> Low state                     this is line 16
    gpioSetOutput(AUXIO_O_GREEN_LED);
}

if (oldState != state.high) {
    // Signal the application processor.
    fwGenAlertInterrupt();
}

// Schedule the next execution
fwScheduleTask(1);

scs says that "state.high =1;" and " state.high =0; " lines are wrong. I am using Sensor controller studio version 2.6.0.132
