Roll a dice using JavaScript in qualtrics

Hi all, I am new to using Java in qualtrics and I would appreciate your help. I want to roll a dice once and to store the result as embedded data to use it later in the survey. The dice rolls well, BUT I CAN'T STORE THE RESULT. These are the steps that I followed. 1- In the beginning of the survey flow, I created a new field: result_matrix_embedded (I did not set it equal to any value) 2- This is what I wrote in the JavaScript of the question: I am using some code that I found online from Philip Tschiemer Qualtrics.SurveyEngine.addOnload(function() { // Required for the callback functions to work. var self = this; // For our comfort, the common settings are predefined. var value_set = [ {key:"1",probability:1}, {key:"2",probability:1}, {key:"3",probability:1}, {key:"4",probability:1}, {key:"5",probability:1}, {key:"6",probability:1} ]; var images = { base_url:'https://www.descil.ethz.ch/projects/1305-SensQuest/dice/img/', ext:'.png', init: 'qmark1.png' }; new Dice("dice1","throw1",{ possible_throws: 1, value_set: value_set, images: images, result_callback: function(throw_nr,result_key){ Qualtrics.SurveyEngine.setEmbeddedData('result_matrix_embedded'+ throw_nr, result_key); } }); }); 3- This is what I wrote in the HTML: <strong>Are you ready to roll the dice?</strong><br /> <br /> If yes, roll the dice below by clicking on the button. <br /><br /><br /> <script src="https://www.descil.ethz.ch/projects/1305-SensQuest/dice/dice.js"></script> <div style="position:absolute; left:200px;"> <div id="dice1"></div></div> <br /> <br /> <br /> <div style="position:absolute; left:179px;"> <button id="throw1">Roll dice</button> </div> * This part works. I can roll the dice and it shows a value. Now, I want to store the result. 4- In another block I write, a text question: This is the result: ${e://Field/result_matrix_embedded} And it doesn't show anything!. The result is not stored in the field. Qualtrics.SurveyEngine.setEmbeddedData() seems to be not working. I tried many other JavaScript codes to roll a dice, but I never manage to store the result. If you happen to know any other way rather than this code, it would be highly appreciated! Thank you!
