How could I have forgotten Czechoslovakia?! Will correct - thanks. I wrestled with West Germany, but officially East Germany was merged into the continuing Federal Republic (FRG), so I decided to omit West Germany.

Question to Quizmaster. Is there a way to avoid losing the % correct score when a line is added to a quiz? This quiz has been taken 60 times in a few days, but from %ages it appears only to have been tried 3 times, because I added a couple of lines after first posting. It seems to me that it should retain the earlier % correct score for the ORIGINAL lines. Inserting a new line is different to CHANGING a previously incorrect answer.
