Adding a custom animation GUI?

So, I've been working on a game recently and I need to add an animation GUI, e.g. custom dances, I googled it and I can't find anything that works.

I add the screenGUI, TextButton and LocalScript although the scripts I use don't work when the button is pressed.

If someone could help me, it would be greatly appreciated.

You can use the MouseButton1Click event, it will then you can load the animation into the player from the local script.
