Hi! Im Floosed a game developer on ROBLOX, This might seem like easy but im very confused. Im trying to make the button below make a frame visible. But the button is inside of a Billboard GUI. If anyone can share how to do this, anything is appreciated! 
Create a separate ‘SurfaceGUI’ for the button that you’re trying to make, though could I possibly know what exactly are you trying to do for the Billboard UI that you’re showing?
I’d put a local script inside of the frame you want to show for the player. Then inside that local script make a function where if the button from the billboard gui is clicked, it will make the frame visible.
