Viewing static text in a GUI

I’m a novice programmer and trying to implement code that I found online. In the AboutWindow, all of the static text is overlayed on top of each other. However, there’s a “Next” button that should scroll through the various lines of text. When I use the “Run” feature to view the GUI, the “Next” button doesn’t work. How do I enable this?

I doubt anyone will be able to help without seeing the project or at least the code you are using.

Can you post code?
