If radio button is selected then text field shows up

[SAGE33108554j4bf]

hello,

I'm brand new to JavaScript and Adobe form fields,
I create a form with five radio buttons "Option 1, "Individual," "Option 2, "Couple," "Option 3, "Single parent" "Option 4, "Family" "Option 5, "Waives" and a text field" (please specify)".
I want the form to show a text field (please specify)", (and become required if possible) if someone selects the radio button option 5 "Waives", but I don't want it to appear as an option if he chose “Option 1,2,3,4,”.

What is the best way to do this?

Thanks in advance

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.

Let's say radio buttons are named "Group1", (change to your actual name) use this as custom calculation script of text field:

event.target.display = this.getField("Group1").valueAsString === "Waives" ? 0 : 1;
event.target.required = this.getField("Group1").valueAsString === "Waives" ? true : false;

As Mouse Up action of checkbox:

this.getField("textField").display = event.target.value == "Off" ? display.hidden : display.visible;

hi, thks it work:) I did the same thing with certain radio buttons. If I accidentally check it and want to clear the form, the checkbox won't become hidden again. Can you assist me with it? 

thanks in advance

For radio button it won't work like that because you can't uncheck radio button.

You need to use calculation script in text field or hide checkbox with a same button you reset radio buttons.

Check my first post above for calculation script.

This one liner will not work.
