check box equals a value in form when checked

I am creating a form that adds amounts for a total. I want to create a check box (BOX1), that when checked, puts a specific dollar amount in another text box (#4) which is then added to other amounts to create a total for purchase.

Correct answer Thom Parker

right now the script is in the actions/run javascript in Box1 and the data in box4 is read only.

You mean that the script is on a MouseUp "run a JavaScript" on the Box1 checkbox?

Ok, then the script should look like this:

if (event.target.isBoxChecked(0))
      this.getField("BOX4").value = 4; 
else
      this.getField("BOX4").value = 0;

Hi,

Something like this should work for the checkbox part :

if (this.getField("BOX1").isBoxChecked(0)){
this.getField("BOX4").value = 4; // dollar amount
}

Then you can just calculate the fields as normal,

see here for more information - https://community.adobe.com/t5/acrobat/field-calculation/td-p/10314382?page=1

That works great.. thanks... however, if i 'uncheck' the box the amount stays in Box4.... do i need another script that says if uncheck, value is '0' ?

where does one find these scripts or how to make them? is there a list somewhere?

Good afternoon, I have a small pdf trying to work some calculations for membership options and values. I have tried the script below and was able for the amount to show up correctly, however when I click off the same box the value does not change and the check mark seems to not work consistently.

if (event.target.isBoxChecked(0))
      this.getField("BOX4").value = 4; 
else
      this.getField("BOX4").value = 0

Full disclosure my skills at java are minimal but will try to figure it out with some guidance.

Thanks

It looks like you want the amounts associated with all check boxes added up? If this is true, then the solution provided on this thread is not suitable.

Instead, set the export value of all the check boxes to the associated amount. Then use the sum function on the Total field to add the checkboxes. And be sure to delete all of the MouseUp scripts. This is critical. Get rid of those scripts.
