Set aiming via animation montage

Hi, I’m making an aim function for my character blueprint. First I made an animation montage using the starter animation pack’s idle ironsight animation, then I made a bool variable that goes true when I’m pressing right mouse button, finally I set up a custom event which plays the animation montage ( and print on the screen some stuff like “you’re aiming” )so that when I hold down rmb the animation montage should play,I know that later I’ll need to set some other stuff for stopping the montage etc… but for now I just need this, the problem is that when I press rmb all is ok (and I can see the printed words on my screen) but animation montage,seems like it is ignored and I don’t know why. I hope someone can help me , I know my english is not perfect so if you need some screenshot because you didn’t understand something just ask.

Thanks in advance :wink:
