Would this be the correct way to write this?

Thanks for answering my other question! I informed a friend of how helpful this website was. We are doing the same project (translating a line from a song into a language of our heritage) and she also has an Italian heritage! The line she is translating is "If I had wings." She used the translator on iGoogle and it said you would write it as "se avessi le ali." Is that correct?
Again, thank you so much for your help! =]
