Be aware that Premise uses an enhanced version of VBScript; it adds the object-oriented concept of "this" and many methods to manipulate Premise objects. In Builder, check Premise Help's Contents for "Premise Home Control Builder > References" for more information. If you want the documentation in Word format, I can post a copy for you.
