Every attack montage in your game must have “Parry Attack” Notify. It used to identify if said attack can be parried or not. (This is very important)

Add the Parry Attack notify to your attack montage and set all details values as per your Data table.

Keep in mind the row name in your data table must match name in your notify. The system will print “counter name is missing” if you accidently didn’t put one or mismatch it.
