I have added animated hamburger. How do I link my old menu?

I have added an animated hamburger. But it is not linking up with my original menu. If I go on my page I can click and it animates but it does not bring my menu up. It seems like the original is still there because there is a tiny spot where I can click and it brings up the menu. But I wan't that gone and it to be linked to my new hamburger.

I am a complete novice. So if you can explain simply.
