Okay, let me explain this a little better.

I can't reissue the @ SAY, at least I don't think I can, because the screen where the change needs to happen to the @ SAY is not the active screen at the time. What I want is for the @ SAY on the screen to be updated while I am sitting on a different screen which makes a company selection, which company will be reflected on the other screen. Now, how do you do that? I don't want to have to reissue the DO screenname.
