[SCRIPT] Basic Light change wont work... please help

[reper1210]

I have no idea why it should have worked but it did. how are you supposed to know exactly what to use in every thing you need to script? its not like the tutorial i used that tried to fade the lights gave me all that extra stuff you just gave me. for example what does the &in part do?

thanks for all the help so far, and unless you learned on this website can you send me a tutorial or website where you learned? noob to pro was good but confusing and doesn't have what i'd like to make.
