Trouble passing indicator value to another indicator.

Hi,

I am not sure what I am doing wrong here. I am trying to pass a value from a multi symbol indicator to another indication. This will be a panel eventually, with the ability to

see different trade signals coming through on the one chart.

The primary indicator is working as it should.

But the sample panel indicator is returning NaN values.

        public int shortPeriod { get; set; }
