UI Button order

Hi,

I am making a game where the user can click the settings-button to slide down the mute-button.
The animations work just fine but if the mute-button is behind the settings-button nothing happens, when I press the settings-button(mute-button ist transparent before clicked). I tried to use GUI.depth but it didn´t worked. The settings-button is also in a higher position in the hierachy.
How can I fix this problem?

Does your button component have interactable checked? One good way to find info is to select you eventsystem gameobject, press play and then(sometimes) drag that gray bottom bar up in the eventsystem component. There should be alot of data where you mouse is moving, on what element and what is selected at the moment. It is a quite a nice tool.
