em-dashes again

I had a problem with the em-dash on the first test and I still can't figure out how to make one on my computer. I have it correct once (but that might have been from the original text and had nothing to do with me), but the rest of mine didn't turn out. I Googled it and it says to use two hypens and that will make an em-dash, but mine won't change. Any suggestions?

Also, is that how I would use "Google" as a verb? :P
