How do you calculate multiple fields in a Form?

Question

Hi,
I have a spreadsheet with several headings and several fields as illustrated below, and description of each field and calculation required is listed below.
Rate Per Day
Days
Course
Attending
Total
$1,000
2
Course A
Yes
$2,000
$2,000
1
Course B
Yes
$2,000
$5,000
5
Course C
No
$2,000
2
Course D
Yes
$4,000
Total:
$8,000
Rate per day:  Field value is inputted by us.
Days:  Field value is inputted by us.
Course:  Field value is inputted by us.
Attending:  Is actually a check-box that the client ticks.
Course Total:  This should be the calculation of RATE PER DAY * DAYS IF ATTENDING BOX IS CHECKED
Total:  Sum of above COURSE TOTAL FIELDS
We currently do this in EXCEL 2007, however we looking at converting it to a PDF Form for distribution to our clients to we can track responses, etc.
My question is really ery simple ... how do I create the above calculations in a form that I want to distribute??  This possible?? If so how (please bear in mind I'm not a developer

Answer 1

In re-reading your question, I realized you're using a check box. In that case, you will need to create a custom calculation script using JavaScript.
Something like:
// This is a custom calculation script
(function () {
    // Get the value of the check box
    var v1 = getField("Attending1").value;
    if (v1 !== "Off") {
        var v2 = +getField("Rate1").value;
        var v3 = +getField("Days1").value;
        // Sum the two field values and set the value of this field to the result
        event.value = v2 + v3;
    } else {
        // Blank field if checkbox is unchecked
        event.value = "";
You'd replace the field names I used with the field names you're using.
This leaves out checking to see if the corresponding Couse field is filled-in, and you'll have to use a custom Format script if you want the type of formatting you show.
