Updating text input value when radio button is unchecked

I have a form where a radio control when checked displays a box with a default no of 1. that works great with a dynamic event of show when radio control is checked.

What I need to do is reset the textbox value to 0 when the radio control is unchecked. I can’t seem to find a way to do this. Is there any kind of local conditional if/then logic within wappler, not in server actions where I know its possible?

thanks,
Rick
