adding attack delay + attack cooldown + attack animation to entity all not working

i made an NBT tag that decreased by 1 every tick, and i wanted to make a procedure to make it so an entity has an attack delay and cooldown when it attacks another

this is what it looks like https://ibb.co/XRG49k7 

its supposed to check if the entity that attacked is the right one, check if its on cooldown or not, and so cancel the original attack and replace it by playing an animation + playing a noise, dealing damage to the entity (both delayed) and adding the cooldown 

if the entity attacked but the cooldown isnt over it cancels the attack

the problem is that it just cancels the entity attack without doing any of the things i set in all cases. Someone help please

and changing 'entity attacked' to 'before entity is hurt' doens't work
