Error When Pressing "Play Button"

Hello, I get an error when i click the play button. It says: All compiler errors have to be fixed before entering play mode

the error is:
Assets/Standard Assets (Mobile)/Scripts/tapcontrol.js(39,26): BCE0018: The name ‘ZoomCamera’ does not denote a valid type (‘not found’).

I am new to unity so any help would be much appreciated, thank you.

you are missing a script or a part of a script

specifically you are missing a script/class/struct named ZoomCamera
