Components in one view cannot access components in a different view. Full stop. You will need to use messages or session custom properties to pass the information.

You will need to study these two topics in the docs to decide which approach to take:

[https://docs.inductiveautomation.com/display/DOC81/system.perspective.sendMessage](https://docs.inductiveautomation.com/display/DOC81/system.perspective.sendMessage)

[https://docs.inductiveautomation.com/display/DOC81/Session+Properties](https://docs.inductiveautomation.com/display/DOC81/Session+Properties)

With `sendMessage`, your dropdown script will assemble a payload with the necessary information and send it to page or session scope. The map component will need a matching message handler that can then extract the information from the payload and apply it to the map.

If you choose to use a session property, you simply assign to that property in your dropdown script. In the map component, you would bind to the session property to handle the data (many approaches).

(And search this forum for examples.)
