Hi,
Actually you are passing "final" to your Scale elements’ log commands, when it should be "last" (reference). Ironically, passing "final" instead of "last" causes a bug that prevents logging any (and so, a fortiori, the last) choice when several choices happened on the same scale
Also note that you still have the ill-formed test on the Scale element(s) I mentioned above which allows participants to click the button and proceed without having made a selection on all the scales, in which case you would also not see lines in the results file for unselected scales
