Adobe Acrobat Pro 2017: Averages, avg of averages, ignore blanks, ignore unchecked

Good Afternoon,

I've tried to use the below formula from TYR67 on a form I'm making for my Sleep Clinic and ran into some errors I was looking for some help to square it away.

/*

    @17537118

        aFields : an array of the field names to use for the calcluation

        bIgnoreBlanks : a boolean that tells the function whether or not to ignore blank fields

        bIgnoreZeros : a boolean that tells the function whether or not to ignore zero values

*/

function calcAverage(aFields, bIgnoreBlanks, bIgnoreZeros) {

    var total = 0;

    var n = 0;

    for (var i in aFields) {

        var f = this.getField(aFields[i]);

        if (f==null) {

            console.println("Error! Can't locate a field called: " + aFields);

            continue;

        }

        if (f.valueAsString=="" && bIgnoreBlank) continue;

        var v = Number(f.valueAsString);

        if (isNaN(v)) continue;

        if (v==0 && bIgnoreZeros) continue;

        total+=v;

        n++;

    }

    if (n==0) event.value = "";

    else event.value = total/n;

}

 

You can then call it from the field's calculation script like this:

 

calcAverage(["Field1", "Field2", "Field3"], true, true);

__________________________

There were errors finding fields and as per forum suggestions I changed:

var f = this.getField(aFields);

to

var f = this.getField(aFields[i]);

Now the only error I get is:

ReferenceError: bIgnoreBlank is not defined
31:Document-Level:calAverage.

 

*no clue what I'm doing and just winging all of this...

I ended up making check boxes and radio buttons to perform the same function, just to test the script on a different kind of choice selection....

 

anyhow,

I have a form and part of it calculates FOSQ-10(Sleep Quality/ quality of life)

If  a question is blank then it only averages checked values that aren't zero.

I'd like all slots to be blank as well until filled out (so we can print a copy for patients)

form template: Q 1-2 get averaged, Q 3,4,5 averaged, Q 6,7,8 averaged, Q9, Q10.

each of those five sections are averaged together if answered, if 0 or unanswered they aren't included in average.

then final # is multiplied by 5....resulting in a # from 1-20.

 

-Besides the (ReferenceError: bIgnoreBlank is not defined
33:Field:Calculate.),

I find that the form doesnt calculate until Q10 is answered (or all the questions from q1-10 are answered)(calculation order is correct)

...if the check boxes are all selected, but then one is changed to zero, that change isn't reflected...

 

Thanks for any help you can provide!!

It's greatly appreciated.

Sorry about that... If you would point me to where you found it I'll fix it there, too.

Can anyone show me were these scripts go into the form would be a great help.

The function should be placed as a doc-level script, via Tools - JavaScript - Document JavaScripts.

The correct code is:

function calcAverage(aFields, bIgnoreBlanks, bIgnoreZeros) {
    var total = 0;
    var n = 0;
    for (var i in aFields) {
        var f = this.getField(aFields[i]);
        if (f==null) {
            console.println("Error! Can't locate a field called: " + aFields[i]);
            continue;
        }
        if (f.valueAsString=="" && bIgnoreBlanks) continue;
        var v = Number(f.valueAsString);
        if (isNaN(v)) continue;
        if (v==0 && bIgnoreZeros) continue;
        total+=v;
        n++;
    }
    if (n==0) event.value = "";
    else event.value = total/n;
}

Trying to get a Document level script and a field script that ignores blanks but includes 0 in the averages. Any suggestions would be helpful!
