Hi All,
I'm trying to develop an app that will have data taken from 3 different SharePoint Lists and have the ability to show them on the app in a popup container. Currently the below image shows what the screen will look like.

On this page I have three lists in vertical galleries;
- Left List - Client Profile
- Right List Top - 'Client Environment'
- Right List Below - 'Access Assessment'
I currently have an Items condition that will filter the specific data relating to the person on the left
Filter('Client Environment',ClientID = ClientSideCar.Selected.ID)
The above currently works but what I would like to do is have the right lists show the populated data on a form housed within a popup.
I currently have the onselect command set to
UpdateContext({ShowPopup: true});
Which will show a popup as seen below.

The item command is
ClientAssessmentGallery.Selected
in what I hoped would be the same command used in the primary screenshot to display the data of the client.
What I want this to do is to able to show the data from the 'Access Assessment' Sharepoint list where the ID matches the selected person (left side gallery) and for it to be displayed within the container.
Any help would be greatly appreciated!
