Hi BCBuizer
Thank you for your answer
I'm sorry, I was not clear
I was able to create 2 screens :
First with Accounts list on the left and edit form on the right -> ok
Second with Contacts list on the left and edit form on the right -> ok
I'm able to create and change and Account and a Contact
When I select an Account, I want to open the Contacts list that are linked to an Account, and I think that it works fine : Navigate(Contact_Screen,ScreenTransition.Fade,{_Account: Gallery_Customer.Selected.Account})
What I don't understand is, when I'm creating the Contact, how to link this Contact to the Account. I was expecting to found a field AccountID. I believe I have to use 'Company name' but I don't know how to populate this field with the Account ID I receive in parameter
I tried to add a field 'Company name' in my Contact edit form, and in the field I have the message 'Add an item with the insert'. And I don't find what I have to do
