rgroup selected toggle

Hiya!

How can I set which one of the rgroup toggles is set?
Meaning how in code can I set lets say the middle one (two) to having the toggle button.

     rgroup .vert |Set| FRAME vertical
    add tag |one| call |!this.stuff()|
    add tag |two| call |!this.stuff(|
        add tag |three| call |!this.stuff(|
     exit

!this.vert.???
Tried setactive and active, etc...

Thanks for any help!

Hi Metzger !

You can use:

!this.vert.val = 2

To select the second toggle for example.

Thank you!
