parenting eyes to bone

Hi! Iv’e finished my character and I can’t figure out how to parent the eyes to the head bone so that they stay in place while the head moves. I’ve placed a copyLocation constraint on the eyes pointing to the head bone but they do not remain in their sockets. What am I doing wrong? is there another way of doing this? hanks

I found the solution, using the constraint “child of”, instead on copy location
