How to add Comment function to NRTR_ATR_STOP window?

New comment
 

I have been using the NRTR_ATR_STOP indicator, and would like to put the current values of the indicator lines into the top left hand corner of the screen. This would make it easier to use as a trailing Stop Loss level. At present, I have to use the mouse and the Data Window. I have used the Comment function successfully on other indicators, but, although the coding here is simple in format, I have not been able to get it to work. Could anyone assist me with this?
