Setting a Checkbox Export Value to a Value in another field.

Hello! How might I go about setting a Checkbox's exportValue to the value placed in another text field? The value in that text field will change periodically, so I would want that exportValue to change with it.

I have a D&D character sheet that auto-sums the skill checks. The checkbox will represent if a character is proficient with said skill. So if that box is checked, I want it to add the proficiency bonus.

Thank you!

The export value is set with the "exportValues" property, but this property must be an array, cause it's used for radio buttons as well.

Put this script in the Validate script for the field that will set the check box export:

this.getField("Checkbox").exportValues = [event.value];

Don't forget to change "Checkbox" to the name of your fields

I am having a similar issue...

 

 From: https://dnd5echaractersheet.com/wp-content/uploads/2017/10/DnD_5E_CharacterSheet-Form-Fillable.pdf 

 

 

I am trying to get the Acrobatics (Acrobatics) box to total up the Dexterity Modifier Box (DexMod) and if the check box (Check_Acrobatics) in front of it is checked, add the Proficiency Bonus (ProfBonus) for a total that can change depending on the number in ProfBonus. In this example it's a 3, so should total a 5.

The Acrobatics Box is currently using a Calculate formula that is auto generated:

 

I tried using this solution of this.getField("ProfBonus").exportValues = [event.value]; in the Check_Acrobatics check field export value:

 

But it doesn't autocalculate from a 2 to a 5 when it is checked...

 

This is exactly what the OP was asking to do, even if perhaps he didn't explain it clearly for a Non-D&D player to understand...  That when a box is checked, it change the skill (Acrobatics) based on the Stat Modifier (DexMod) plus the Proficiency Bonus (ProfBonus) if the check box (Check_Acrobatics) is checked, and just the Stat Modifier (DexMod) if the check box (Check_Acrobatics) isn't checked.  I hope I explained our problem adequately.

 

If I put a 3 in the Check Box's Field Export instead of the this.getField("Checkbox").exportValues = [event.value]; then it does give me a 2 or a 5 depending on how the box is checked or unchecked...

I provided a custom javascript calculation script. It won't work in simplified field notation.

 

You need to make sure the field names are correct, but there is an error in the code. I missed referencing the field value on one place. Here's the correction

 

event.value = this.getField("DEXMod").value;

if(this.getField("Check_Acrobatics").value != "Off")

    event.value += this.getField("ProfBonus").value;

 

Whenever something related to scripting doesn't work in Acrobat, then the very first thing to do is to look in the JavaScript Console. If there's an error reported there, then tells about it when you post to the forum.

Here's a tutorial on the Console Window:

Sometimes JavaScript thinks the values are strings instead of numbers. In this case it concatenates the values.

Here's a redo of the script that guarantees the values are treated as numbers

 

event.value = Number(this.getField("DEXMod").value);

if(this.getField("Check_Acrobatics").value != "Off")

    event.value += Number(this.getField("ProfBonus").value);
