# Calculating number of filled fields

Hi all,

Long time lurker, first time poster. I am working in Adobe Acrobat Pro 2017, and created a fillable PDF for employee appraisals. To calculate the employee's score at the end of the form, I need to calculate the number of fields where text was entered (like the Excel "COUNTA" function) so I can divide that by the added total of ratings. I have everything figured out except the custom calculation script for totalling the number of fields that have text entered in them. I've spent the past 8 hours deep in the weeds in Google and this support community and have found numerous similar scenarios, but I can't get any of those scripts to work. I'm old, my brain is fried, I know zilch about JavaScript and would really, REALLY appreciate any insight or help.

For reference, the fields are named COM.01 through COM.18, and I just need to count the total number of fields containing text, leaving out any COM. fields that are blank.

See if this works for you:var total = 0; var fields = this.getField("COM").getArray(); for (var i=0; i<fields.length; i++) { var f = (fields[i]).valueAsString; if (f !="") total++; } event.value = total;

You can use this code as the custom calculation script of your text field:

``````var total = 0;
var fields = this.getField("COM").getArray();
for (var i=0; i<fields.length; i++) {
if (f.valueAsString!="") total++;
}
event.value = total;``````

If you want it to immediately display the relative amount of filled-in fields to the total, change the last line to:

event.value = total/fields.length;

Thank you very much. I copied and pasted that into the field where I need the result, but nothing happened when I entered text into the "COM." fields.

Change the value of one of those fields and then check the JS Console (Ctrl+J) for error messages.

If you can't figure it out please share the file with us for further help.
