Hi! Thanks in advance for any help. I have a survey that users will return to each week over a 16 week period. I created a multiple choice menu with 16 options - one for each week - and branching for each “lesson” according to which option they select. Ideally, I want a user to only see “lesson 1” as a menu option during their first 7 days in the program. On the 8th day, I want them to see “lesson 1” and “lesson 2”, and so on through the end of the intervention, such that on day 106, they see all lessons, including “lesson 16”. I tried to accomplish this by using embedded variables based on adding X number of days to their STARTDATE variable, assigned at screening, ie: WEEKTWO = ${date://STARTDATE/c/+7%20day}With help from chatgpt, I then tried to use javascript to accomplish this time-delayed branching, but nothing has worked. Any ideas on how to accomplish my goal? Thank you so much!

@rooperSure. Replace the START value with this piped text:And slightly adjust the code to consider “/” instead of “-”:Qualtrics.SurveyEngine.addOnload(function() { var startDateStr = "${e://Field/START}"; // Format: MM/DD/YYYY // Parse the start date var startDateParts = startDateStr.split("/"); var startDate = new Date(startDateParts[2], startDateParts[0] - 1, startDateParts[1]); // YYYY, MM-1, DD // Get today's date var today = new Date(); // Calculate the difference in days var diffTime = today - startDate; var diffDays = Math.floor(diffTime / (1000 * 60 * 60 * 24)); // Determine how many list items to show var weeksSinceStart = Math.floor(diffDays / 7); // Select the list items var listItems = document.querySelectorAll("#" + this.questionId + " .QuestionBody .ChoiceStructure .Selection"); // Hide all list items initially listItems.forEach(function(li) { li.style.display = "none"; }); // Show the appropriate number of list items for (var i = 0; i <= weeksSinceStart && i < listItems.length; i++) { listItems[i].style.display = ""; }});The embedded data should be placed before the first question so that the current date is set for START when the survey is started.BestChristian

Hey @rooper.nice challenge. I tested it with this question:Implemented this code and added it as JavaScript to the multiple choice question:Qualtrics.SurveyEngine.addOnload(function() { var startDateStr = "${e://Field/START}"; // Format: MM-DD-YYYY // Parse the start date var startDateParts = startDateStr.split("-"); var startDate = new Date(startDateParts[2], startDateParts[0] - 1, startDateParts[1]); // YYYY, MM-1, DD // Get today's date var today = new Date(); // Calculate the difference in days var diffTime = today - startDate; var diffDays = Math.floor(diffTime / (1000 * 60 * 60 * 24)); // Determine how many list items to show var weeksSinceStart = Math.floor(diffDays / 7); // Select the list items var listItems = document.querySelectorAll("#" + this.questionId + " .QuestionBody .ChoiceStructure .Selection"); // Hide all list items initially listItems.forEach(function(li) { li.style.display = "none"; }); // Show the appropriate number of list items for (var i = 0; i <= weeksSinceStart && i < listItems.length; i++) { listItems[i].style.display = ""; }});And in the survey flow before the multiple choice question block I defined some embedded data field START in format MM-DD-YYYY:This date is the first date of the first week of your lessons. In my example, I let it start 2 days ago. Taking the survey results in this view:If I change START to 07-15-2024 and let it start one week earlier:Change to 06-17-2024:Change to some date later than today:Hope I could help!🙂BestChristian
