Awesome Oscillator On Top adding William R

HI Team

I am writing Indicator for combination of AO + William R

Is anything wrong on my Code?

If commented my william R code it will display AO

However, If i have both results only showing William R Indicator results.

Can someone help me here whats went wrong on my code.

[Parameter(DefaultValue = 5)]
        public int periodFast { get; set; }

        [Parameter(DefaultValue = 34)]
        public int periodSlow { get; set; }

        [Parameter("WRPeriods", DefaultValue = 25)]
        public int WRPeriod { get; set; }
        [Output("Main", LineColor = "CornflowerBlue", Thickness = 2)]
        public IndicatorDataSeries WResult { get; set; }
        [Output("previousAO")]
        public double previousAO { get; set; }

        [Output("currentAO")]
        public double currentAO { get; set; }

        [Output("Awesome OscillatorGreen", IsHistogram = true, LineColor = "Green")]
        public IndicatorDataSeries AwesomeGreen { get; set; }

        [Output("Awesome OscillatorRed", IsHistogram = true, LineColor = "Red")]
        public IndicatorDataSeries AwesomeRed { get; set; }

        private SimpleMovingAverage smaSlow;
        private SimpleMovingAverage smaFast;
        private IndicatorDataSeries medianprice;

        protected override void Initialize()
        {
            // Initialize and create nested indicators
            medianprice = CreateDataSeries();
            smaSlow = Indicators.SimpleMovingAverage(medianprice, periodSlow);
            smaFast = Indicators.SimpleMovingAverage(medianprice, periodFast);
        }

        public override void Calculate(int index)
        {

            //William R start
            double max = Bars.HighPrices.Maximum(WRPeriod);
            double min = Bars.LowPrices.Minimum(WRPeriod);
            double close = Bars.ClosePrices[index];
            WResult[index] = 100 - (100 * (close - max) / (max - min) * -1);
            //William R End

            //AO Calculate value at specified index           
            medianprice[index] = (Bars.HighPrices[index] + Bars.LowPrices[index]) / 2;
            previousAO = smaFast.Result[index - 1] - smaSlow.Result[index - 1];
            currentAO = smaFast.Result[index] - smaSlow.Result[index];
            if (previousAO >= currentAO)
            {
                AwesomeRed[index] = smaFast.Result[index] - smaSlow.Result[index];
            }
            else
            {
                AwesomeGreen[index] = smaFast.Result[index] - smaSlow.Result[index];
            }

        }
