How to enable an extra text-field when radiobox y=YES is chosen?

Hello,
​
I would need instructions how to enable (show) another field when someone chooses y=Yes from a radiobutton. I know how to do it with the checkbox (or separate checkbox lines), but cannot find info how to do the same with radiobutton. Can someone explain please! Thanks!

It's exactly the same as for the checkbox, just using the VALUE (not the label) of the radio, and using the selecting / unselecting event.

Sorry I do not understand... the checkboxes are all separate boxes (at least I did not find a way to add all checkbox values into one field).
​
I need exact details what to add to each field. I have tried different ways but nothing seems to hide the text-field when radiobutton is either not chosen or n (NO) is chosen.
Below you see the images. The field_opiskeletko is the radio group with the following options:
y=Kyllä opiskelen
n=En opiskele
​
If they choose "y", then I want the next field "opintolinja" to show up.
​
With these details, what exactly do I add and to what tab/field?
​
Thanks!

You see the part on number 1 where you've left "affected elements" blank?

Hi,
added, no change, the field shows up at first load.

​
p.s. any change of getting pictures of an example?
​

You need the other part, the HIDE event when unselecting.

Thank you!
Even with this comment, I had to test and try different settings before I got it work...

You know if you'd just sent me an image from start...we would have both gotten it faster/easier. 😃

Over and out!
