Hi,
I am not sure I understand and sorry I don't real others posts, or watch peoples videos (we have limited time since we answer things for free).
1. Is your App Model driven or Canvas App?
2. Is this data across 4 screens going to the same Row in the Table?? Or will you create multiple rows?
It sounds to me that you are .... sort of doing a Wizard thing, or a Business Process, that takes them across screen to screen
This mean you have a few options
Option 1
Let's pretend you are filling in data and clicking like a Next Button to get to the next screen
You could pass a Collection, to the next screen which represents the first screens data, and you would do this across all the screens
From 1 to 2
Navigate(ToScreen2, Transition.None, { Screen1Data: CollectionOfScreen1Data})
From 2 to 3
Navigate(ToScreen2, Transition.None, { Screen1Data: CollectionOfScreen1Data, Screen2Data: CollectionOfScreen2Data})
From 3 to 4
Navigate(ToScreen2, Transition.None, { Screen1Data: CollectionOfScreen1Data, Screen2Data: CollectionOfScreen2Data, Screen3Data, CollectionOfScreen3Data})
The benefits here are you aren'ting creating global variables
Option 2
Define a Collection that has either A) Sections fo reach screen, or B) Properties for everything
Then Pass this to each screen, and instead of the above you only pass 1 thing, and each screen fills in their data and passes it along
Option 3
Create a Global Variable Collection That holds it all, like Option 2 but you dont pass it, its just global
Option 4
Don't create multiple screen.
On 1 Screen, create 4 Containers. Build your pseudo Screen in that Container
When the person starts up the visible property of Container1 is visible and all others are invisible
each time they click Next, you make the next one visible
Option 5
You build a Collapsible Pattern were all sections are visible at one time but accordion collapsible.
Option 6
Build 4 Canvas App Components in your Project, its easy and all low code
In the Only Screen drop your 4 components, and just like Option 4, make them visible as needed
I don't know which one you works best for you but these are all options.
