Attachments control Items property invalid

[cooper33]

I have an Attachments control in my PowerApp. I am displaying an Item's attachment on an item detail screen. Navigation to the screen is from a gallery connect to a SharePoint list. On my detail screen, in the Items property of the attachments control, I have 

Gallery_Name.Selected.Attachments

to attempt to display the item's attachments. I have used this before on another PowerApp and it has worked. The error I'm getting is Name isn't valid. This identifier isn't recognized. This error appears most commonly when a formula refers to something that no longer exists (for example, a control you've deleted).

I double checked that the SP list has attachments enabled. Several list items already have attachments. I also refreshed my data connections and tried 

Gallery_Name.Selected.'{Attachments}'

but nothing has worked. Any suggestions?

Is the Items property of your Gallery a datasource or a collection?

If it's a collection, you will need to lookup the attachments for your attachment control as they don't come into a collection.

Thanks, it was a collection. I used Lookup with the gallery item's ID to get the item directly from the datasource
