checkbox or radio conditioned upon value in another field

[Wissam5FBB]

Hello, I am a beginner. I have a value that is a weight in "kg" to be entered on the PDF form I want a checkbox or a radio button to be ticked automatically depending on 3 ranges of the weight entered:

• <1kg
• 1-3kg 
• >3kg

I would appreciate it if you could help me to script that, and where to enter this script? Thanks

(if the weight entered in the form is 2.5kg for example, only the second radio button should appear automatically)

Thanks

What's the name of the radio-button fields, and what are their export values?

[Wissam5FBB]

the names of the radio buttons are

rb1

rb2

rb3

the corresponding values:

1.5 mL

3.25 mL

5 mL

What about if the "kg" field is empty?

PS. you should either convert the fields to check-boxes or give them all the same name.

[Wissam5FBB]

checkboxes should be Ok too

If you use check-boxes with the same names and export values then you could use this script as the custom validation script "kg" to achieve it:

var kg = Number(event.value);
this.getField("rb1").checkThisBox(0, kg<1);
this.getField("rb2").checkThisBox(0, kg>=1 && kg<=3);
this.getField("rb3").checkThisBox(0, kg>3);

Fantastic! it worked very well, thanks a lot.

I have another variable that is a simple mutiplication of 2 others, and I want the result if exceeding numer 3, to just give the number 3 itself:

A*B=C

if C>3 then C=3

Thanks a lot for your support and help.

As the custom calculation of "C" enter the following:

var v = Number(this.getField("A").valueAsString) * Number(this.getField("B").valueAsString);

event.value = Math.min(3, v);

[Wissam5FBB]

Great! 

If I want the result of this script to run at "C" only when I check a checkbox named "CB1", how should I add this condition? 

Thanks for your patience.

[try67]

Do you mean it should only show this result if CB1 is ticked?

[Wissam5FBB]

yes exactly

[try67]

So what should the value be when it's not ticked?

[Wissam5FBB]

it should be empty

[try67 · Accepted solution]

You can use this, then:

if (this.getField("CB1").valueAsString=="Off") event.value = "";
else {
var v = Number(this.getField("A").valueAsString) * Number(this.getField("B").valueAsString);
event.value = Math.min(3, v);
}

Wonderful!

Thanks for taking me patiently step by step, I do appreciate your help.

I learned from you and I am grateful to you.

Thanks

kg can't be empty and can't be zero
