Thanks Dennis. I think I was getting confused because I was debugging
an indiactor with DeBugView and I could see that the indicator code
was being called when I changed the selector line and was being called
with BarCount-1 = to the position of the selector line.
Anyway I think the easiest way maybe to just use Ref(Array,-1).
Thanks
