I'm putting together control for multi-zone temperature control using a Zone Template. I have indirect addressing, using a template parameter 'string' called "Zone". All the zone parameters are in the same AOI data type in Studio 5000, so indirect addressing is working great. I have a "basic" template screen that's visible on the main page, but I'd like to open a pop-up window and pass the "Zone" string to the custom parameter used on another template placed on that pop-up window. This pop-up has all the "details" of the zone. I can't quite figure out the strategy to do this. I'm guessing it's in scripting, but I'm striking out so far. I'm sure this is a pretty basic action, can you help me understand how to do it? ---

Your popup window will need a parameter that you'll pass it when you open the popup. You'll then need to pass that to your template embedded on that popup if I'm understanding you correctly. ---

"You'll then need to pass that to your template embedded..." Yes, I understand that. I don't know _how_ to pass it. ---

To pass the parameter to your popup, there's an option to pass parameters: [https://docs.inductiveautomation.com/display/DOC81/Popup+Windows](https://docs.inductiveautomation.com/display/DOC81/Popup+Windows) Then on that popup, you'll bind your template custom parameter to your custom parameter on the popup. ---

Great, thank you very much!!! I knew I'd seen it before, but I didn't expect it on the Navigation tab. I looked right past it, over and over.
