Try this sample. Once the variables are set to True or False, the JS sorts them and places them on the second page. Variables that are blank don't show on the second page.  If you need more explanation, please ask.

    Hi and thank you for getting this started Walt! There was one issue I found with the javascript, so to get it working the == "true" part needed to have the quotes removed: var player = GetPlayer();
    var correct =[];
    var inCorrect =[];
    var selections =[];
    var j=1;
    var k=1;

    var NOP = ["", "Jaw Thrust maneuver", "Oropharyngeal airway", "Nasopharyngeal airway", "King (multi-lumen) airway", "Laryngeal Mask Airway (LMA)", "Endotracheal tube", "Cricothyroidotomy"];


    selections[1] = player.GetVar("JawThrust");
    selections[2] = player.GetVar("Oro");
    selections[3] = player.GetVar("Naso");
    selections[4] = player.GetVar("King");
    selections[5] = player.GetVar("LMA");
    selections[6] = player.GetVar("ET_Tube");
    selections[7] = player.GetVar("Crico");


    for(i = 1; i < 8; i++){
        if (selections[i] == true) {
        correct[j] = NOP [i];

        j++;
        }  else {
           inCorrect[k] = NOP[i];
        k++;
        }
        }

    for(i = 1; i < 8; i++){
        if (correct[i] != null) {player.SetVar("Correct" + i, correct[i]);}
         if (inCorrect[i] != null) {player.SetVar("Incorrect" + i, inCorrect[i]);}
                  }
