I'm making an App for simplifying my inventory system. On the first page "BrowseSD7" I have my "GallerySD7" linked to an Excel table "SD". When I click on a piece I want to see the details, the app bring me to the page "DetailSD7" and in the "FormViewerSD7" it's supposed to show me 4 info wich are four "DataCard". In the "Item" I putted "Gallery.SD7.Selected" but it makes an error. All of this is a copy paste of a test I made earlier and everything worked on it. I comparred both side by side and every bit of code is identical (except for example GalleryTEST changed to GallerySD7). Now when I click on a piece in the "GallerySD7" I only have a blank screen. It would be very kind if someone could help me with that problem.

Hi @kb25,

This error message indicates that your data source is invalid, you must make sure that the data source you populated the FormViewerSD7 with is the same one you populate the GallerySD7 with.

GallerySD7.Selected
