Thanks Graham,
I'm slowly making my way through this. I don't
have to use an IF. And won't again.
Now it seems that barindex() is
not a number. As in Close[Barindex()-i]. Sure looks
like a number to me.

<SPAN

was once a Boolean is no longer a Boolean. I am trying to find a conditional
variable that IF likes.

is to start a loop within FOR <SPAN
