Punch Animation not firing help?

Hello this if my first time posting to really any forums anywhere at all so I hope this works. I have recently started enjoying UE4 and doing many tutorials. Most of the time they work out or I can work backwords and recheck my work to solve me problem. Alas this isn’t one of those times.

I attached copies of my work below, I have the inputs set to LMB and it is firing with a IsValid node as well. when I play nothing happens at all no punching. I have tried double checking all the section names from Anim montage match up with the “montage set next section”. Also I dont believe it is the slot because when I try to delete it a notification comes up saying this slot is in use in a BP. Thank you anyone for the advice , cheers.
