Hi @Anonymous ,
We shuold define the corresponding properties in the formula bar of the respective properties.
So if you want pass the gallery selected item to Form's Item property, you should make the definition in Items property formula bar.
As mdevaney said, there are two ways to get that:
1. Directly, set GalleryX.Selected to Items of Form
2. Use variable to pass the Gallery selected item, put Set(Var_selecteditem, ThisItem) to Gallery's OnSelect, and then set Var_selecteditem to Items of Form.
Best regards,
