Complex scoring of a form and sharing it with the user - example

I wanted to score the SF-36, a popular general physical and mental health questionnaire and share the results with the client. I needed to solve two main issues: How to do the scoring and how to do the workflow so that there would be the least amount of disruption and a user would receive a pdf with all 10 scores listed (8 primary and 2 summary scores). The scoring was done by javascript as I couldn"t see how Math alone could do the job. The scoring feature didn"t work as it only shares one score in the end, even though you can calculate at least the 8 primary scales (I didn"t check whether the 2 summary scores could be done). The latter was achieved by using a timing question, in a block of its own at the end, which runs the javascript on load and moves to the next question after 1 second with the text "Calculating scores ...". In the next block was a text paragraph giving the scores and by clicking on "next", the user received a pdf with the scores at the end. Here is the javascript Part 1. I expect to put the second part (message too long otherwise) as an answer: ``` Qualtrics.SurveyEngine.addOnload(function() { /*Place your JavaScript here to run when the page loads*/ /*Place your JavaScript here to run when the page is unloaded*/ // PF var v1 = parseInt("${q://QID13/SelectedAnswerRecode/1}",10);
