Make field mandatory based on radiobutton selection

[Angelique2023!]

I have a group (Group2) of radiobuttons with 3 options.
Option1

Option2

Option3

When Option1 is selected I want field Text14 to be mandatory. When option 2 or 3 are selected it should not be mandatory.
I have tried putting code in mouse Up/Javascript

if (event.target.value == "Yes")

{this.getField("Text14").required = true;}

But it's not working.

What am I doing wrong here?

Use also a else

I tried this

if (event.target.value == "Yes")

{this.getField("Text14").required = true;}
else

{this.getField("Text14").required = false;}

but still not working

Your choice is 'Option1' not "Yes".

Use this as custom calculation script of the field you wish to make required;

event.target.required = this.getField("Group2").valueAsString === "Option1" ? true : false;

Thank you this worked perfectly

Thank you for your previous help. I'm still working on the same form, but needed to add an option.

I have a group (Group2) of radiobuttons with 4 options.
Option1

Option2

Option3

Option4

When Option1 or Option4 are selected I want field Text14 to be mandatory. When option 2 or 3 are selected it should not be mandatory.
I've been working with if, or, else. but I can't seem to find the right code

Use this as custom calculation script of that text field:

var rb = this.getField("Group2").valueAsString;
event.target.required = (rb === "Option1" || rb === "Option4") ? true : false;

Thank you for your help. The form works so much better already.

What if I want to make a field mandatory based on 2 groups?

So if Group 2 option 1 is true and Group 4 option 2 is true

[Angelique2023!]

and is it at all possible to make a group mandatory bases on an option chosen in another group.

I noticed the groups don't have the custom calculation field

If you need a custom calculation script, you can place it in any text field, you can even make a text field and hide it and place script in it. Let's say you want to make Group5 required, depending on selections from Group2 and Group4, a custom calculation script:

var g2 = this.getField("Group2").valueAsString;
var g4 = this.getField("Group4").valueAsString;
var g5 = this.getField("Group5");

g5.required = (g2 === "Option1" && g4 === "Option2") ? true : false;
