Hi ProrokC2. Welcome to SubSim.
I assume that when you mean zoom you are referring to the periscope view. if you are using OLC 'Gold' MkIId Gui then the zoom does not work. That's the way he made it and I believe it has something to do with his included environment mod. For that reason I have always used his other Gui OLC Gui 1.2.7. In it you can zoom the periscope view.
Also since you are new you should become familiar with SubSim's language policy which prohibits the use of asterisks to replace letters in swear words.
