Fill in the fields with the information selected and reset the form when exiting.

Let me explain my problem:

When I click on the "edit" button of my Gallery : 

I get the Reference which is the primary key of my article and I put it in the variable "Ref" :

If(
    Gallery3.Selected.Etape.Value = "Identification";
    (
    Navigate(Identification; ScreenTransition.None; {SelectedGalleryItem: Gallery3.Selected; Ref:Gallery3.Selected.Référence})
    );
    Gallery3.Selected.Etape.Value = "Qualité";
    (
    Navigate(Qualite; ScreenTransition.None; {SelectedGalleryItem: Gallery3.Selected; Ref: Gallery3.Selected.Référence})
    );
    Gallery3.Selected.Etape.Value = "Appros";
    (
    Navigate(Appros; ScreenTransition.None; {SelectedGalleryItem: Gallery3.Selected; Ref: Gallery3.Selected.Référence})
    );
    Gallery3.Selected.Etape.Value = "Logistique";
    (
    Navigate(Logistique; ScreenTransition.None; {SelectedGalleryItem: Gallery3.Selected; Ref: Gallery3.Selected.Référence})
    );
    Gallery3.Selected.Etape.Value = "Marketing";
    (
    Navigate(Marketing; ScreenTransition.None; {SelectedGalleryItem: Gallery3.Selected; Ref: Gallery3.Selected.Référence})
    );
   Gallery3.Selected.Etape.Value = "Commerce";
    (
    Navigate(Commerce; ScreenTransition.None; {SelectedGalleryItem: Gallery3.Selected; Ref: Gallery3.Selected.Référence})
    )

)

With this, I can change the line corresponding to the reference with the form.

What I want to do is to be able to see the other forms that are each in a different screen. (Each form makes up part of the line to be modified/or completed)
For now, my data is only displayed on the screen I am navigating to. The others are either empty or filled with the information from another line that I have previously modified.

As you can see, it displays me only the infos of the line Where "Ref" is 5 and in the Screen named appros because ETAPE = "Appros".

Im displaying infos with this : 

i put all the datas of the line in SelectedGalleryItem and after i diplay it on the form :

(also all my forms are in Edit mode apart  the first one which is in New mode because it creates me a new row.

What I want to do is to be able to see the other forms that are each in a different screen. (Each form makes up part of the line to be modified/or completed)
For now, my data is only displayed on the screen I am navigating to. The others are either empty or filled with the information from another line that I have previously modified.

The informations that is put in the fields after clicking on the edit button stays there until I press the edit button again from another line which changes the form information.

I would need that all the information of the line is not only displayed on the screen where I go but that it is displayed on all the forms concerned by the information, to be able to navigate between the screens to consult the information on the different forms.

Once I have finished viewing and completing my form, I click submit and the information is sent to the sharePoint List.
I would need this button to have a function that would allow Reset my "Ref" and that all my forms reset.

So I’ll summarize my need:
- Be able to reset my "Ref" variable as soon as I submit the form
- The home button must also empty all forms but also reset my "Ref" variable
- Be able to display all the information of my line in all my forms concerned (one form per screen)

And aslo here is the code already used in my button :

(for me "," is ";" and ";" is";;"

Home Button : 

Navigate(Home)

Submit Button :

If(FormQualite.Valid;
    Patch(
        'Log Creation Produit';
        LookUp('Log Creation Produit'; Référence = Ref);
        FormQualite.Updates
    );;
    Patch(
        'Log Creation Produit';
         LookUp('Log Creation Produit';Référence = Ref);
        {Etape: {Value: "Appros"}}
    );;
ResetForm(FormQualite);;
Navigate(Home);
Notify("Le formulaire n'est pas valide. Veuillez renseigner les champs obligatoires")
)

I know it’s a bit long, but if you have any advice or a solution, please let me know.

Thanks

I managed to fill all the forms of differents screens, i switch contexte varible to global variable.

Now i can Reset my Ref i just do : Set(GlobalRef; "")

But the forms are not reseting, in my button home i do this to reset :

Set(GlobalRef; "");;

If(
    GlobalRef = "";
        (
        ResetForm(FormIdentification)
        &ResetForm(FormQualite)
        &ResetForm(FormAppros)
        &ResetForm(FormLogistique)
        &ResetForm(FormMarketing)
        &ResetForm(FormCommerce)
        &Navigate(Home)
        )
)
