Accessing a Control

Question

I am doing some of my first GUI C# programming. I have a program.cs and a form.cs code files. I have a refreshData() function that I want my button to call. It works if I use [code] RSSGuiVersion.Program.refreshData(); [/code] However, at the end of the function I want my function access a label called "currentSong" and change its text. How do I do this? I've tried [code] RSSGuiVersion.Armitunes.currentSong.Text = "a"; [/code] And I get An object reference is required for the nonstatic field, method, or property 'member' For the life of me I do not know where to go next.
