Hi Anthony,

Copied and pasted and applied, but absolutely no change in the
results.  First bars still blend to background color.

The only way I seem to be able to fix this is change the background
color, but that is exactly what I don't want to do.

BTW, thanks for the example anyway.  I didn't realize I could nest
IIF like that, which (I guess) gives the effect of if, then, else.
