How do I set embedded data in visual conjoint?

Question

I would like to implement an experiment where participants see one image of a male politician and can click a button to see the second image of a female politician. The var_att1 describes what is on the iamges, the only difference is the gender of the politcian. The first image is chosen randomly from an array of 9 image-URLs, the second image is randomly from an array of 9 image-URLs.The only thing I cannot figure out is how to save embedded data based on which two images are displayed. With this code, I get the same two values (Women topic_ every time, no matter which images are displayed.Thank you for any help! Qualtrics.SurveyEngine.addOnReady(function () {  var URLsM = [    "https://unibaslabss.eu.qualtrics.com/ControlPanel/Graphic.php?IM=IM_LblPTYNEYLtDJyH",    //all URLs for the first image go here ];  var URLsF = [   "https://unibaslabss.eu.qualtrics.com/ControlPanel/Graphic.php?IM=IM_JA5a82GOXq7423l",    // all URL for the second image go here];var att1 = ["No appeal_No appeal", "General topic_No appeal", "Women topic_No appeal",                      "No appeal_Depict men", "General topic_Depict men", "Women topic_Depict men",                          "No appeal_Depict women","General topic_Depict women", "Women topic_Depict women"];// Shuffle the array of URLs to randomize the ordervar randomF = Math.floor(Math.random() * URLsF.length);var randomM = Math.floor(Math.random() * URLsM.length);    var att1_pic1 = att1[randomF];var att1_pic2 = att1[randomM];Qualtrics.SurveyEngine.setEmbeddedData('att1_F', att1_pic1);Qualtrics.SurveyEngine.setEmbeddedData('att1_M', att1_pic2);var el1 = document.getElementById("i1");el1.src = URLsF[randomF];// Add event listeners to the buttonsvar buttonNext = document.getElementById('nextProf');buttonNext.onclick = function () {el1.src = URLsM[randomM];};var buttonPrev = document.getElementById('prevProf');buttonPrev.onclick = function () {el1.src = URLsF[randomF];};// Example for jQuery button click eventjQuery('#buttonNext').on('click', function () {/* change embedded data */Qualtrics.SurveyEngine.setEmbeddedData("cb", "yes");});});
