I'd find out exactly what the screen object names are...
Put in some code to set the form caption to be the name of the form after they are instantiated so you can double check what thier names are when they run. I'd recomend agaisnt calling them screen2 or the like. Better to assign them specific names when they are created so you know for certain how to reference them.
