If it is your own class or function you just need to add it to your path, but you didn't give us any information as to what 'Screen' is supposed to be or what you expect. The error message is very clear.

I suspect you're trying to use the third-party Psychophysics Toolbox but you have not installed that toolbox. If that's the case, see the installation instructions on the Downloads section of the Psychtoolbox website I linked above.
