# Calculating the total of linked Checkboxes and numeric text fields

Hi all.

I am very new at this but I am in desperate need of help. I am creating an Adobe form where I want to calculate the money value in a text field that is only calculated when the checkbox is ticked. I have come up with this code to do it and it is kind of working but not 100%.

event.value = 0;

if (this.getField("SCB1").value != "Off")
event.value+= (this.getField("S1").value);

if (this.getField("SCB2").value != "Off")
event.value+= (this.getField("S2").value);

if (this.getField("SCB3").value != "Off")
event.value+= (this.getField("S3").value);

SCB1 is Checkbox 1 and S1 is the text field

I was so excited that this was working until I started adding more SCBs linked to Ss. Instead of creating a running total in the subtotal text field, it is doing something weird. When I check SCB1 with '50.00' in S1, the total show '50.00' but when I add a check to SCB2 with '50.00' in S2, the total shows '5050.00'.

This is literally my first code that I am writing and I don't know how to fix it. If you can help within the next day or two, it would be a huge help!

Use this:

``````var total = 0;
for(var i=1; i<=3; i++){
if(this.getField("SCB"+i).valueAsString !== "Off")
total += Number(this.getField("S"+i).valueAsString);}
event.value = total;``````

If you add more fields, just replace '3' with the number of fields you have.

In text field, go to 'Validate' tab and enter this script:

if(event.value == 0) event.value = "";

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Yes! Thank you so much! Works perfectly!

I have another question as well. I have tried a number of different scripts for this but none seem to be working.

I want to populate a numeric value from a dropdown box selection into multiple text fields with each text field having a different number but blank if nothing is selected. The dropdown box I am using as an experiement is called 'Heatingsystem' with the items 'Gas' and 'Solar' and the text Fields are 'S1', 'L1' and 'V2'.

If you can help, that would be great!

Use this in dropdown field as 'Validate' script and replace numbers with actual numbers you wish for those fields:

``````var S = this.getField("S1");
var L = this.getField("L1");
var V = this.getField("V2");

if(event.value == "Gas"){
S.value = 1;
L.value = 2;
V.value = 3;}

else if(event.value == "Solar"){
S.value = 4;
L.value = 5;
V.value = 6;}

else{
S.value = "";
L.value = "";
V.value = "";}``````

You can also use it as 'Calculate' script but then pay attention to field calculation order.

Thanks for this but it is only kind of working. If I select 'Gas', nothing populates but if I select 'Solar', the numbers do populate in the right place.

Thanks for this. I am having trouble using this in another text field. It worked for the first two text fields (Subtotal A and B) but it is not working for C. I changed 'SCB' to 'LCB' and 'S' to 'L', which worked but when I did it for 'VCB' and 'V', it didn't work. Would I have to change the names of those boxes for it to work or am I doing something wrong?

Check console for errors.

If you use script for different fields, you also need to change field names.

I got it working. There were some gaps in the sequence of text and checkboxes and once I fixed this (by adding hidden boxes named in numbered sequence), now both scripts are working perfectly.

Hopefully these are the two most complicated that I need and that my boss doesn't ask for a more complicated one that might see a modification of the dropdown formula (hopefully they don't ask!).

Hi Nesa,

You have been a huge help but I have just one last challenge and I have tried to find the solution for the last couple of hours (again).

I have 3 dropdown boxes with export values added to the selections. I would like to select an item in each DB and have the export value added together and populate a text field. I can do this with a simple 'sum' calculation but I would like the text field to be empty, not with '0", when the option - select - is selected in the box.

I also want to do this for the two DBs as one is the item (with export value price) and the other is the number of items they want (multiplier). Again, the simple product function works but I would like - Select - to leave the text field empty, not with a '0".

Is there a way to do this?

Hi Nesa,

You have been a huge help but I have come across another problem that my boss has given me.

They would like me to populate a text field from either a dropdown box OR a text field. The text field will be fillable with a number and the dropbox has values added on to the options. I have tried a number of different options again but cannot get it to work. It is complicated as the line is to be dropdown box OR ______per sqm x No. of sqm = text field total.

I found a simply way to do it as two separate entries but my boss would like it on one line.

Any help would be appreciated!

For multiplication, you can use built in option under 'Calculate' tab select Product(x) and pick your fields.
