Why wont this physics.arcade.overlap() work?

[fanheader]

Can anyone help me figure out why the physics.arcade.overlap() isn't working in this code? 

 

thanks in advance

[CodeToWin]

what do you mean by isn't working? 

[fanheader]

the  bulletHitEnemy() function isn't firing off when the bullet hits a goblin

[CodeToWin]

do all sprites have enableBody set to true?
