 /** Configure Analog WatchDog 1
 */
 AnalogWDGConfig.WatchdogNumber = ADC_ANALOGWATCHDOG_1;
 AnalogWDGConfig.WatchdogMode = ADC_ANALOGWATCHDOG_SINGLE_REG;
 AnalogWDGConfig.HighThreshold = 20;
 AnalogWDGConfig.LowThreshold = 4;
 AnalogWDGConfig.Channel = ADC_CHANNEL_1;
 AnalogWDGConfig.ITMode = ENABLE;

 {
 Error_Handler();

    Thanks very much; that was the issue. I didn't see that "rank" can expand.
