Montage set next section not working

Hey, I am currently calling an animation montage through an animation instance. This plays the first attack for a melee combat system. In the first attack I have a notify which checks if the attack button has been pressed again. If it has then it should play the next attack. This attack is in it’s own section. However although I am entering both section names correctly into the montage set next section node, and it is called. The animation is being played. If anyone can help me it would be a massive help.
