Excellent!

I didn't know the {} existed, but it was exactly what I was looking for.

Thanks!

I have ten sentences (and therefore ten words that I need to save to make a new sentence). I put a for loop around the extraction script, but I can't figure out how to save the word decoded from each sentence. my variable 'word' is simply overwritten every time I go through the loop.
