Remapping Y and Z keys with Karabiner

I just want to switch the Y and Z keys. I've tried everything with Karabiner on High Sierra, but it just doesn't seem to work. I always get an error message along the lines of: "Karabiner Error. Error in xml. Unknown symbol: KeyCode::0x6" Attached you can see the code that I've been trying to use, as well as the modifier keys for Y and Z (which I've tried every variation of in the code). Swap Space and Tab private.swap_z_and_y __KeyToKey__ KeyCode::0x6, KeyCode::0x10 __KeyToKey__ KeyCode::0x10, KeyCode::0x6 strong text Please help!
