Hello, I want to add a counter which could count the number of sub-string "ab" and "ba". That is , participants type letters in a text bar, like "ababaaaabbbbba", and I want to count the number of "ab" or "ba" and show it on the screen on Qualtrics. In the example, there are 3 "ab" or "ba" in this string, so the he or she will see "3" on the screen. I will be appreciate if anyone can tell me how to write the Javascript.

Hello @Anna999 ,Please follow the below steps:Step 1: Create two embedded variables ( eg: ab_freq, ba_freq)i.e one for frequency of 'ab' and another for frequency of 'ba' and set there values as 0.Step 2: Paste the below code in the js(onReady) of Text entry question type. var that =this.questionId; jQuery("#"+that+" .InputText").on('blur',function(){ var temp = this.value; var count = (temp.match(/ab/g) || []).length; Qualtrics.SurveyEngine.setEmbeddedData( 'ab_freq', count ); count = (temp.match(/ba/g) || []).length; Qualtrics.SurveyEngine.setEmbeddedData( 'ba_freq', count ); });Step 3: The above code will set the number of occurence of 'ab' in "ab_freq" embedded variable and of 'ba' in "ba_freq" embedded variable.
