Hi,



A beginner on JS on Qualtrics.



I am designing an experiment where the subjects have a series of 10 questions to answer. They face one question per page. For all questions, the answer has to a numerical number. A the start, they are given 1000 points (or usually called "tokens" in experimental economics). For each question, they are free to "spend" from 0 to 100 tokens maximum.



I am looking for a javascript which will provide a "token counter" where on the first page the counter display on the screen "1000 tokens" and then at each page, the counter is updated in light of their answer.



Here is what I want, example:

1. On Page 1 : display "1000 tokens".

2. They answer question 1. Say, they "spend" 50 tokens. They click on "next page".

3. On page 2: display "950 tokens".





How would you do that?





This seems the right inspiration or not? https://www.qualtrics.com/community/discussion/144/how-do-i-show-the-number-of-words-in-text-entry-boxes-i-have-several-on-the-page







Many thanks for your help!
