Need Help with mono develope

Ok, So im am following a guy on scripting and he is using UniSciTE while i am using mono develop, he writes the script and i copy it into mine word for word i go and check the console and i have about 5 errors, and i have the EXACT same thing as him, so i try a copy and paste method and same thing happens, i get about 5 errors, i don't know what it is wrong but if someone could be kind enough to get back to me on this much would be appreciated

Thanks,
