Assuming that you would like to use only one generic control page (Play, Stop, etc...) to control any of the three changers, here is a suggestion in its simplest form. You could make it more complex as needed.

- Three Firm keys could be used on that page to set a variable "changerNum" to "Changer1", "Changer2" or "Changer3". It would be wise to display which Changer is currently set somewhere on the page.

- On a specific control button ("Play", for example), use the variable to execute the corresponding action on that specific Changer's hidden page. You would have one specific such page for each changer, with all the functions on that page pointing to the proper device. Let's say that the Changer1 hidden page is called "Changer1", and the Play button on that page is called "PLAY", you could code the following Prontoscript command in the Play button on your single generic page: CF.widget("PLAY", changerNum).executeActions();

I have 6 Scientific Atlanta set top boxes which I control in this fashion from a single set of channel logo pages.

Hope this helps.
