Many thanks to this.
-I moved (whichtense) also for the fillers MC following the same codes and it works fine. but they still have NA for the three columns CQcorrect, RQcorrect, MCcorrect although I set that in my pcibex script.
-I also moved choose(for nationality) and choose2 (for English level) and that worked in the correct_which_results but appear with NA in the main tmp ! I do not really know why!
I tried also to have a column of the groups which defined by the PennElementName (TextInput2) but I got this message:
Error: Each row of output must be identified by a unique combination of keys.
Keys are shared for 144 rows:
Although I deleted row number 10 because it has the same name (TextInput2) of row 11, but that did not solve the problem.
Sorry I feel that become more into R area instead of pcibex but I would appreciate your help in that.
