Scoring text entry in Loop & Merge

Question

I have one question regarding how to score a "text entry". In my study, participants study image-name pairs and take a test. In the test, I show them the image, and also the first letter of the name, participants should input the missing part of the name in the text entry blank. I use loop & merge to do this. Please see the attached picture. Field 5 is the first letter of the name. Field 6 is the correct answer. I want to compare participants' input with Field 6 (the correct answer). But it seems that the scoring function in Qualtrics could not achieve this. The logic is clear. If the "text entry" equals to ${lm://Field/6}, then score = 1, if not, then score = 0. I think maybe a JavaScript is helpful. But I have no knowledge about how to write a JavaScript. Is there anyone who can help me? I will be very much appreciated.PS. I can add a feedback using the display logic. If the input = ${lm://Field/6}, then display the text "you are right". I tried to think this question in another way: to calculate how many times this feedback is displayed. That equals to the correct score. But I can't find a way to calculate the display times of a question. Help!!!!

Finally I figured this out based on Loop & Merge with Scoring (text box) — Qualtrics Community.It is important to firstly set an embedded data named "score" and set its initially with 0.Qualtrics.SurveyEngine.addOnPageSubmit(function() {score = Qualtrics.SurveyEngine.getEmbeddedData('score');var input = $(this.questionId).select('.InputText');var answer = input [0].value;var solution = "${lm://Field/6}";if (answer === solution) {score++;}Qualtrics.SurveyEngine.setEmbeddedData("score", score);});Qualtrics.SurveyEngine.addOnReady(function(){/*Place your JavaScript here to run when the page is fully displayed*/});Qualtrics.SurveyEngine.addOnUnload(function(){/*Place your JavaScript here to run when the page is unloaded*/});

Hi Tian, I believe one of our resident Qualtrics Wizards, TomG, has already provided a solution on another post that should address your query.Cheers,Cameron
