For instance let we put an arrow from existing method images in first

That will do it!

This can also be used for coloring cell content appropriately. But for

Thank you...the WebGrid is truly useful.  What did you think of my post last

WebGrid for now, but it's nice to have the nil values sort without causing a
DNU...

Thanks again.
