I was testing the differences between the various Bible Harmony options in this interactive tool.
1. View is set to default, translation in set to NRSV, have been testing with John 20:11-18 and was most recently in the Eusebius canons.
2. Set Harmony to Cox and Easley. Note that Section 160 is at the top i.e. Jesus Faces Herod Antipas.
3. Click on go arrow in reference box to see if that takes you to the correct passage ... nope still at Jesus Faces Herod ...
4.Look down the list to find correct entry 173 to prove that an entry does exist ... open it and it looks fine ... so no idea why the harmony won't focus properly

Same problem appears on Robinson ... seems to be an issue of the nonconsecutive/missing references
