Hey guys,

Never mind, but thanks alot...seems this one was a issue where someone
had cleared the control sequence just before calling setText so no control
ID's where retained and this threw me off.

Darned code!

I couldnt explain this until I started to write a better demo for Derek
so Derek, you indirectly solved my problem.....Thank you!
You read this bubbashrimp your program is fixed....
