How can I access a variable defined in Modifiers Tab in Button's JScript?

@errante Thank you. Your example works but I was unable to get this to work when passing multiple values. For example, when using two arguments like this: VALUE/O,VALUETWO/O DummyCommand returns &value& &valuetwo instead of the variable's values.

Otherwise, it looks like this solution would work (for me) if we could find a way to pass several values.
