Identifier expected unity ошибка

Basically I’ve been trying fix this error for ages so I can actually look at thee game in play mode. It is a script for enemy AI who will chase the player around.

The error is at (90,32) which is attempting to transform the enemys vision when they attack the player

The line that is creating the issue is transform LookAt(player);

Any help would be much appreciated.
