Oh lol yeah sorry did that in a hurry, you can't just separate different /say commands via a space because it thinks that's still part of the text you want to say, so in this case you would need to use the = notation. Also I got the order wrong. So the correct line without a linebreak would be:
Parent.Button.OnPress='say ' ## (y) ## ' say ' ## (y) ## ' say ' ## (x) ## ' say ' ## (x)
But I thought so that your question was mainly directed at the linebreak anyway.
