I have 2 questions about updating the list. First question. I have a SP List of products where one of the columns is Choice type with product status and the other contains the name of the responsible seller. In the App, I have a form inside a Gallery that allows changing the status of the product in a combobox, with the help of the Patch function. However, I want that when someone accesses this screen with the form and changes the product status to "Free", the seller's name is deleted, so that the product becomes "free" and the seller's field is null.
Second question. After the above function is solved and it is possible to access a product that is "free" and with null seller registration, I would like that when the user changes this status, the seller field receives the user's name. As an example, after accessing the product that was free and changing its status, the SP List will show the User name and status equal to that sold. I imagine you use the Patch function.
