Hi Daniel,
I have developed and attached a quick demo for you.
The excellent "Learning SetupBuilder Part I" is the official "Everything you ever wanted to know about SetupBuilder but were afraid to ask" introductory material, written by Jane Fleming. This "SetupBuilder Bible" is a compendium of tips, tricks, warnings, and resources for SetupBuilder users of every ability level. It demonstrates how the powerful SetupScript scripting language provides built-in interactivity to custom dialogs in SetupBuilder 7. Custom dialogs can exhibit different behaviors based on end user input. Each custom dialog lets you perform script actions in response to certain events inside a dialog.
Does this help?
