Hi, all. I've searched the forum and couldn't find anything close to my question, so I'd appreciate it if someone could offer some suggestions. I have created a hidden equation/question that sums the scores for an anxiety scale which I called {Anxiety} and I've got that reporting the total fine on a text display/question. I assume that in addition to being able to show participants their scores at the end of the survey, this information will also be stored in the database. Here's where my question comes in. The creator of the test suggests that scores should be compared to the mean scores of other participants before ranking their anxiety level. So basically I'm wondering if there is a way to count the number of {Anxiety} scores that have been stored, then sum them before dividing them by the total count. I then need to be able to display the mean score with participant results.

To do that you will need to use JavaScript and make an AJAX call to a remote PHP script that queries the database for previous answers and calculates the "mean-to-date". (a fair amount of coding required)
