I don't know how to explain this

I'm having a problem with my boss IA, so I created this nbt number called "IA" and every tick it adds 1 to it, when this number gets to certain amount it will do an attack. But for some reason that I don't know why, it only repeat the same attack that is when the IA is on 900 since the beggining, and everything beside it works really well, if someone experient could join a discord call or something like that to help me I will be very greatful!
