How to compare rank of objects from previous ranking task

Question

Hello, for my study I have the respondents rank (drag and drop) 9 soft drinks according to their preferences. Peach IT and Lemon IT are two of the previously ranked items, and in the next question I want to display the one  that got the higher ranking among those two. How can I do this using Javascript? Thanks

Hello @Maria_Mich ,Following solution will work for Rank order(Drag and Drop) question typeSuppose your Peach IT and Lemon IT are first and second choice while designing your question type as shown below:!Step 1: Create an embedded data(HigherRank) in the survey flow before Rank order(Drag and Drop) question Step 2: Paste the following code in the js(onReady) of Rank order(Drag and Drop) question    var that=this.questionId;    $(document).on('DOMSubtreeModified', function(){    if(parseInt(jQuery("[id='QR~"+that+"~1'] span.rank").text()) > parseInt( jQuery("[id='QR~"+that+"~2'] span.rank").text())){    Qualtrics.SurveyEngine.setEmbeddedData( 'HigherRank', jQuery("#"+that+"-2-label span").text() );    }else{    Qualtrics.SurveyEngine.setEmbeddedData( 'HigherRank', jQuery("#"+that+"-1-label span").text() );    }    });Step 3: The above code will set the embedded data(HigherRank) with choice with higher rank, and now  in the next question you can pipe in the embedded data(HigherRank)Note: If your option is not in the above(image) sequence, then you need to modify '~1', '-1' and  '~2', '-2' in the above code based on your options position

Hi and many thanks for your answer! In my case the order that the options are displayed for each participant have to be randomized, so I don't have a fixed position for Lemon and Peach to use in this code. What would you recommend in this case?
