Return a "Pass" or "Fail" response based on % of correct answers in quiz.

Question

I have a form which uses radio buttons for each series of questions. I have assigned a value of "1" to the correct response and "0" for the incorrect answers. I need to return a "Pass" or "Fail" response based on the percentage of correct answers. 80% and above = PASS, 79% and below = FAIL.

I have assigned a text box (Text1) to calculate the total of all answered questions, but I do not know how to use that value to come up with a percentage. I am thinking I need another text box (Text2) to run a custom calculation script against the value of Text1. This is where I am clueless as I do not know Javascript. Any help would be appreciated. Also, will Javascript be usable on any platform as I will no control over the end-user's device.

Sorry, that first statement should have beenvar total = +getField("Text1").value;

George_Johnson · Answer

The custom calculation script in the Text2 field could look something like:

// Get the value of the Text1 field, as a number

var total - +getField("Text1").value;

// Set the total number of questions

var num = 20; // Set this number to the total number of questions

// Set this field value based on the percentage correct

event.value = total / num >= 0.8 ? "Pass" : "Fail";

This is really the minimum script, but should get you started. It could be improved a number of ways, for example by only setting a Pass/Fail value when all of the questions have been answered, and something like "Incomplete" otherwise.
