How to calculate cumulative marks in a pdf field?

[jahantech]

I prepare a question paper in acrobat pro. Each ques has check box for correct & incorrect answer. It has a totalmarks field & each quesmark field. What I am trying to do, when a person ticks correct answer check box of any ques then his/her cumulative marks will show in total marks field. I want to implement this for all 10 question of my paper.

Can anybody please help?

Your description is not very clear... Do you have a check-box that says whether or not the question was answered correctly, or do you have multiple check-boxes which are the answers for the question, and the user selects one of them?

Also, what are the names of the fields involved?

Thanks for reply.

I have two check-boxes named "correct" & "incorrect" for each question. Other field are "questionmark" & "totalmarks". From which user will select one of them. If user select "correct" field then it would be "correct" * "questionmark" and result will populate in total marks field.

So there's a single "questionmark" field, or one for each question?

Also, you still didn't specify what are the names of the check-box fields...

Thanks for the reply

For correct question I have check boxes named (“correctq1”, “correctq2”, “correctq3”, “correctq4”, “correctq5”, “correctq6”, “correctq7”, “correctq8”, “correctq9”, “correctq10”)

For incorrect question I have ckeck boxes named (“incorrectq1”, “incorrectq2”, “incorrectq3”, “incorrectq4”, “incorrectq5”, “incorrectq6”, “incorrectq7”, “incorrectq8”, “incorrectq9”, “incorrectq10”)

For all questions I have only one “questionmark” field.

OK, then you can use this script as the custom calculation of the total marks field:

var totalCorrect = 0;
for (var i=1; i<=10; i++) {
    if (this.getField("correctq"+i).value!="Off") totalCorrect++;
}
event.value = Number(this.getField("questionmark").value) * totalCorrect;

Thanks for reply.

WhenI try, it shows SyntaxError:illegal character3:at line 4.

When I use below code

var totalCorrect = 0;

for (var i=1; i<=10; i++) {

    if (this.getField("correctq"+i).value!="Off") totalCorrect++;

}

event.value =

Number((this.getField("questionmark").value) * totalCorrect);

No error shows. In this case if I check or uncheck any checkbox no change in "totalmarks" field whether I change "questionmark" fields value then "totalmarks" fields value changes.

Works just fine for me. Did you copy the code into Word or something like that?

Press Ctrl+J and see if there are any error messages there.
