I have the following code in my ITEMS field for my Gallery, but on any user logged in, I want to only show the items they submitted and I am not sure on the syntax for this in addition to the code below. The pulldown (CHOICE Field) is only available for certain Admin users. So all other user need to see their items from the SharePoint List that they submitted and only be able to submit a new record, which I have a button for that and it works fine.
If(Dropdown2.Selected.Value="Leticia Lamarque",SortByColumns(Filter('Contract Review', 'Assigned To'.Value= "Leticia Lamarque"),"Created",Descending), If(Dropdown2.Selected.Value="Yasaman Moazami-Goudarzi",SortByColumns(Filter('Contract Review', 'Assigned To'.Value= "Yasaman Moazami-Goudarzi"),"Created",Descending), If(Dropdown2.Selected.Value="Pending", SortByColumns(Filter('Contract Review', 'Assigned To'.Value="Pending"),"Created",Descending), Filter('Contract Review', 'Created By'.DisplayName=User().FullName))))
