Putting Scripts On One Line

I've been making some scripts so when I use the DK ability Raise Dead it will play a Headless Horseman sound file. When I made the macro, obviously, it didn't work. So I checked WoW wiki, or whatever they call it, and it said the script had to be on one line. When I make the macro, it forces it to be on multiple lines. How do I keep it on one line? Is it possible for me to have the script on mulitiple lines by having something like " ; " at the end of the line space? I've triple checked all the spelling, the spaces, and the capitalization. That is probably not it, but it is still possible. I will continue to try until I can get it to work.
