Hi Damien, I was using a similar approach, but yours is more elegant, so I have modified mine. Thanks for the info! Best regards,

If you are just asking for a complex number, and you don't mind giving a hint that there might be an imaginary part, you could also use a single numerical response asking for 2 values (ordered), like that: <problem> <startouttext/>Enter 1+2i:<endouttext/> <numericalresponse> <answergroup type="ordered"> <answer> <value>1</value> <value>2</value> </answer> </answergroup> <textline size="5" readonly="no"/> <startouttext/>+<endouttext/> <textline size="5" readonly="no"/> <startouttext/>i<endouttext/> </numericalresponse> </problem> Damien _______________________________________________ LON-CAPA-users mailing list LON-CAPA-users@mail.lon-capa.org http://mail.lon-capa.org/mailman/listinfo/lon-capa-users _______________________________________________ LON-CAPA-users mailing list LON-CAPA-users@mail.lon-capa.org http://mail.lon-capa.org/mailman/listinfo/lon-capa-users
