How to configure show when

Question

So, I need to use visibility/showWhen to display a dropdown if a certain choice of radio button is selected.
The format is kind of like this, the two dropdowns are supposed to be hidden until 'Yes' is selected in the group of the second radio buttons.

This is currently the code I have. I'm still fairly new to Appian and trying to figure things out!
I have experience w/Python/C#/Vis Basic so explaining in those terms could be helpful as well
if(
  a!radioButtonField(choiceLabels: "Yes"),
 	showWhen:true()

You can put any expression into that parameter that evaluates to a boolean. Typically we use a comparison operator like <, >, =.
