Uploading CSV files last weekend I kept getting error reports. These were mostly that the summit code was in the wrong format. I couldn’t see anything wrong with those where the report indicated. After some time and some help I found that stray spaces in the CSV file would cause this. However they were sometimes hard to find! LOL. I also had a QSO rejected as a duplicate when it wasn’t and some problem with dates not being accepted. The database might have been having a bad day, but the spaces thing is worth checking if you have this problem.
