Hi Barry --
The loop is the correct solution.
This statement:
Buy = IIf(ifDate(SelectedValue(DateNum())), 1, 0);
Returned either 0 or 1 -- a scalar -- which was then assigned to the entire Buy array.
Thanks,
Howard

I found a way. I added a for loop around the buy and that works. I
don't understand why I had to do that.
aDate = DateNum();
for (a=0; a < BarCount; a++)
{
Buy[a] = ifDate(aDate[a]);
}
