Verify Signature Routine Not Working (ED25519 Algorithm)

I am using the ED25519 algorithm to create a public and private key pair and to sign some sample text. You can see the example at:

This all works fine but the verify with the public key does not work. My sample code is attached.

I will pay up to $25 for the correct implementation of Verify.
