Mathematical Conditions: Adding field valuesAsked by pixelplaza on October 06, 2014 at 05:21 PM
My form has a quiz with true and false answers. Each correct answer earns one point. How do I calculate a score for each person completing the quiz?
You can take advantage of our calculation widget: http://www.jotform.com/help/259-How-to-perform-calculation-in-the-form.
Or, you can use our quiz app: http://apps.jotform.com/app/quiz_form
Please get back to us if you need further assistance.
The calculation is fine for adding up items in the one field but how do I add up only correct answers from a group of fields?
I can't use the quiz widget as the answer total will be a hidden field so the contestant doesn't know their score. The score will be emailed to the administrator.
What I understand is that you would like to give values to questions depending on their answers? Counting the number of correct answers but not visible to the user/contestant?
You can achieve this by using the "Conditions" feature, then you can have a hidden "Total Points" field to place or add up all the correct items there.
Here are possible tutorial links that may help you:
Here's a sample I did using your form that I cloned.
1. I set up hidden fields that will server as a storage of the value depending on the answers of the user (ex. If he/she answers "True" in question #1 that would equal to 1 point hidden field #1)
2. Set up "Conditions" to identify what is a correct answer and add the corresponding value points to it.
3. Create other condition based from the questions you want to have a value. In my case I have 3 hidden fields named "1", "2" and "3" that will serve as a temporary storage, I will add them up and the value will be showed to the "Total Points" field depending on their answers.
4. These are my conditions.
You can check the working clone here, cloned form. Note: Fill in the "Full Name" section and only questions 1-3 with true or false are working.
If you don't want the users to see the "Total Points" live, you can just hide it.
