Set a Label text in 1st winform page to display on 2nd form page

Im fairly new to C# so please forgive me if my terminology isn't to par. In my winform application I want to grab a name from a MySQL database @ login and display the name on a second page(home.cs). Im currently getting an error which is "An Object Reference is required for the non static field. In login.cs im trying to add something like -> Home.bunifuCustomLabel2.Text = "test"; to set the label in home.cs basically... Login.cs is my 1st loading page and Home.cs is my 2nd page which loads after successful login. I would like to query the database while the connection is open and eventually set the label text for home.cs to display something like Welcome, Name
