Hi @WarrenBelz,
Yes I understand I've definitively have overlooked something. I will be adding a lot more components and am desperate for a solution before I have to do that..
So heres the BrowesGallery1. This is connected to an excel sheet. On select here I have:
Select(Parent)
.
So once you select a property it brings you to Detail Screen1. OnSelect of the pencil icon here is
EditForm(EditForm1);Navigate(ScrComponentScreen, ScreenTransition.Fade)

Which goes to the components Gallery. OnSelect of one of these components is
Navigate(ThisItem.Value.Screen,ScreenTransition.Cover)

So if you click Bathrooms for example you are brought to EditForm2_Bathroom

OnSelect of the next arrow at the bottom right is:
UpdateContext({VarLoading_3:true}); SubmitForm(EditForm2_Bathroom); Navigate(EditForm3_Kitchen,ScreenTransition.Cover)
Which brings you to the kitchen component which is similar to the bathroom screen.
The user can also select the hamburger menu on the top right and the OnSelect command for that is:
SubmitForm(EditForm2_Bathroom) ; Navigate(ScrComponentScreen,ScreenTransition.Fade);
I always navigate to the edit form of the sheet and the Item property for all edit forms are BrowseGallery1.Selected.
