My assumption is I can use "Deselect All" to basically "uncheck" radio button selections?

I use the script builder to drag "Deselect" into my script page. I click on "DeSelect all" and when I go to select the 'field name'.. the drop down is empty.  I have everything from radio buttons, dropdowns, etc on my form and this list is showing nothing.

What could I be doing wrong?

 

I basically want to deselect all items in my Radio Button list when someone changes another field.  I'm putting the code in the "On user input" on the "other field" (not the radio buton).

 

Thx
