Creating a visible word counter for more than one text entry question

I would like to have a visible word counter placed on seven different text entry questions. However, the code I used only works for the first question. Is there code that allows the word counter to work for all questions in a survey? Here is the code I used so far: <span id='wordCountDisplay'>0</span> (to place in the question's HTML) Then put this code in the JavaScript editor Qualtrics.SurveyEngine.addOnReady(function() { var display = $('wordCountDisplay'); var questionID = this.questionId; var textbox =$('QR~' + questionID); var that = this; function countWords(s){ s = s.replace(/\\n/g,' '); // newlines to space s = s.replace(/(^\\s*)|(\\s*$)/gi,''); // remove spaces from start + end s = s.replace(/[ ]{2,}/gi,' '); // 2 or more spaces to 1 if(s == ''){ return 0; }else{ return s.split(' ').length; } } textbox.onkeyup = function(e){ display.update(countWords(textbox.value)); console.log(textbox.value); } }); As I mentioned earlier, I have seven text entry questions, and this code only works for the first question. I need code that allows the word counter to work on all of my questions.
