I don't ever remember making any changes in my Logbook as it seems that imported the data from my "details' page, but maybe not. But yes, you absolutely want to make sure both are correct. I don't know for sure, but I suspect if your QRZ details are correct (zones, etc) that that data will get imported into your logbook once you enable the logbook feature, but maybe not. That could be why he was not able to "save" the zones in the logbook section because that data was controlled by the details section. Would be wise to check and make sure both are correct!! .............Bob
