Cant figure out why animation isnt working



I am trying to make it so that when the player presses play on the main menu, the screen fades to black. I have a black image set up on my UI with the alpha set to 0. I set up an animation that takes .5 seconds to transition the alpha to 1, making the black image fully visible. When I hit play in the animation window it plays fine. I then set up the animation in my event graph and plug it in with the rest of the things to do when the play button is hit. The audio still plays and the level still transitions but the image does not fade to black. Can anyone tell me what I’m doing wrong?
