Why is my envelope distort tool not working?

[rubic79423207]

I've been trying to distort my text into this saxophone silhouette I've created using the pen tool. And yes, the object ive drawn is on top, text is below. I've tried making the text into outlines and it still does the same thing. I've tried flipping the silhouette object and still nothing. It keeps doing this, compeltely illegible; I've even tried doing a more simple silhouette and nothing.
