Hi,
The small program is attached. The labels are displayed but their position
does not change based on the x,y,z values that are provided to them. I could
not see the labels earlier as they were being displayed outside the visible
range of my program. But now the problem is that their position does not
change. I have attached the small program. Thanks once again for all your
help.

With best regards,
Jay
