setting up combo attacks third person melee

I copied the paragon greystones attack animation / combo system.

I copied and pasted that to my own character and my own model , changing the animation montages at the end.
I also added AnimNotifies onto my montages as well, making sure the variables and everything were made corrently too.

Everytime I click left mouse button, instead of playing my animation he like moves backwards and stutters?

but when i watch the graph while clicking mouse one, it shows everything working correctly, only the animations aren’t playing correctly. Any ideas?
