I'm new to Power Apps, just playing around with Canvas Apps to get an idea of what can be done. Can any body help me with the formula I need, on the screenshot below the left hand gallery is connected to D365 Accounts and the right hand gallery links to D365 Contacts. Ideally I want to be able to select an account record from the left gallery and to the right I want the gallery to display only those contacts who are linked to the specific account I have selected. I have tried a few different formulas, however I keep getting errors.
Thanks
